Mark _init and _fini as hidden [BZ #23145]
_init and _fini are special functions provided by glibc for linker to define DT_INIT and DT_FINI in executable and shared library. They should never be put in dynamic symbol table. This patch marks them as hidden to remove them from dynamic symbol table. Tested with build-many-glibcs.py. [BZ #23145] * elf/Makefile (tests-special): Add $(objpfx)check-initfini.out.

elf: Unify symbol address run-time calculation [BZ #19818]
Wrap symbol address run-time calculation into a macro and use it throughout, replacing inline calculations. There are a couple of variants, most of them different in a functionally insignificant way. Most calculations are right following RESOLVE_MAP, at which point either the map or the symbol returned can be checked for validity as the macro sets either both or neither. In some places both the symbol and the map has to be checked however. My initial implementation therefore always checked both, however that resulted in code larger by as much as 0.3%, as many places know from elsewhere that no check is needed. I have decided the size growth was unacceptable. Having looked closer I realized that it's the map that is the culprit. Therefore I have modified LOOKUP_VALUE_ADDRESS to accept an additional boolean argument telling it to access the map without checking it for validity. This in turn has brought quite nice results, with new code actually being smaller for i686, and MIPS o32, n32 and little-endian n64 targets, unchanged in size for x86-64 and, unusually, marginally larger for big-endian MIPS n64, as follows: i686: text data bss dec hex filename 152255 4052 192 156499 26353 ld-2.27.9000-base.so 152159 4052 192 156403 262f3 ld-2.27.9000-elf-symbol-value.so MIPS/o32/el: text data bss dec hex filename 142906 4396 260 147562 2406a ld-2.27.9000-base.so 142890 4396 260 147546 2405a ld-2.27.9000-elf-symbol-value.so MIPS/n32/el: text data bss dec hex filename 142267 4404 260 146931 23df3 ld-2.27.9000-base.so 142171 4404 260 146835 23d93 ld-2.27.9000-elf-symbol-value.so MIPS/n64/el: text data bss dec hex filename 149835 7376 408 157619 267b3 ld-2.27.9000-base.so 149787 7376 408 157571 26783 ld-2.27.9000-elf-symbol-value.so MIPS/o32/eb: text data bss dec hex filename 142870 4396 260 147526 24046 ld-2.27.9000-base.so 142854 4396 260 147510 24036 ld-2.27.9000-elf-symbol-value.so MIPS/n32/eb: text data bss dec hex filename 142019 4404 260 146683 23cfb ld-2.27.9000-base.so 141923 4404 260 146587 23c9b ld-2.27.9000-elf-symbol-value.so MIPS/n64/eb: text data bss dec hex filename 149763 7376 408 157547 2676b ld-2.27.9000-base.so 149779 7376 408 157563 2677b ld-2.27.9000-elf-symbol-value.so x86-64: text data bss dec hex filename 148462 6452 400 155314 25eb2 ld-2.27.9000-base.so 148462 6452 400 155314 25eb2 ld-2.27.9000-elf-symbol-value.so [BZ #19818] * sysdeps/generic/ldsodefs.h (LOOKUP_VALUE_ADDRESS): Add `set' parameter.

S390: Add CFI rule in _dl_runtime_resolve[_vx] for unwinding.
In _dl_runtime_resolve[_vx], unwinding fails after the new stack frame is created as there is no CFI rule for r15. This is also observeable in GDB: Backtrace stopped: previous frame inner to this frame (corrupt stack?) Therefore this patch is now storing r15 on stack and is using cfi_offset rule. The stmg/lmg instruction is used to store/load r14 and r15 with one instruction. On 64bit, the offsets of the fprs have moved to store r15 directly after r14. On 31bit, the r14/r15 is now stored between the other gprs and fprs as the space wasn't used. ChangeLog: * sysdeps/s390/s390-64/dl-trampoline.h (_dl_runtime_resolve): Store r15 on stack and add cfi rule. * sysdeps/s390/s390-32/dl-trampoline.h (_dl_runtime_resolve): Likewise. |

S390: Add cfi information for start routines in order to stop unwinding.
GDB failed to detect the outermost frame while showing the backtrace
within a thread:
Backtrace stopped: previous frame identical to this frame (corrupt stack?)
Before this patch, the start routines like thread_start had no cfi information.
GDB is then using the prologue unwinder if no cfi information is available.
This unwinder tries to unwind r15 and stops e.g. if r15 was updated or
on some jump-instructions.

S390: Save and restore r12 in TLS_IE macro.
The testcases elf/tst-tls1-static and elf/tst-tls2-static are failing on s390 if gcc is configured with --enable-default-pie. According to binutils, there are only four valid cases for IE -> LE transition: lg %rx,(0,%ry) -> sllg %rx,%ry,0 lg %rx,(%ry,0) -> sllg %rx,%ry,0 lg %rx,(%ry,%r12) -> sllg %rx,%ry,0 lg %rx,(%r12,%ry) -> sllg %rx,%ry,0 Thus I've adjusted the TLS_IE macro in s390 tls-macros.h files in PIC case in order to use r12 for the address of global offset table. The adjusted macro definition is not used if gcc is not configured with --enable-default-pie. ChangeLog: * sysdeps/s390/s390-32/tls-macros.h (TLS_IE): Use r12 for GOT address. * sysdeps/s390/s390-64/tls-macros.h (TLS_IE): Likewise. |

S390: Fix build with gcc configured with --enable-default-pie. [BZ #21537]
Building glibc with gcc configured with --enable-default-pie failed on s390 due to assembler messages: ../sysdeps/unix/sysv/linux/s390/s390-32/__makecontext_ret.S:44: Error: junk at end of line, first unrecognized character is `@' HIDDEN_JUMPTARGET was expanded to exit@PLT@GOTOFF. If SHARED is not defined, HIDDEN_JUMPTARGET is defined to JUMPTARGET in sysdeps/s390/s390-32/sysdep.h. There it expanded to exit@PLT in non SHARED case as PIC is defined if gcc is configured with --enable-default-pie. Thus I've changed the "ifdef PIC" to "ifdef SHARED" as we do not want PLTs in the static obj files. I've also changed this in sysdeps/s390/s390-64/sysdep.h. I've also adjusted sysdeps/unix/sysv/linux/s390/s390-32/__makecontext_ret.S. If glibc is configured with --disable-hidden-plt, then NO_HIDDEN is defined. In SHARED case HIDDEN_JUMPTARGET would be expanded to exit@PLT@GOTOFF instead of __GI_exit@GOTOFF. Now we jump to: - __GI_exit if SHARED is defined - exit@PLT if SHARED and NO_HIDDEN is defined - exit if both are not defined. On s390 31bit we have to setup GOT pointer in r12 if we use a PLT stub. Therefore I use SYSCALL_PIC_SETUP from sysdep.h and added the missing semicolons. ChangeLog: [BZ #21537] * sysdeps/s390/s390-32/sysdep.h (JUMPTARGET, SYSCALL_PIC_SETUP): Check SHARED instead of PIC.

PowerPC64 ELFv2 PPC64_OPT_LOCALENTRY
ELFv2 functions with localentry:0 are those with a single entry point, ie. global entry == local entry, that have no requirement on r2 or r12 and guarantee r2 is unchanged on return. Such an external function can be called via the PLT without saving r2 or restoring it on return, avoiding a common load-hit-store for small functions. This patch implements the ld.so changes necessary for this optimization. ld.so needs to check that an optimized plt call sequence is in fact calling a function implemented with localentry:0, end emit a fatal error otherwise. The elf/testobj6.c change is to stop "error while loading shared libraries: expected localentry:0 `preload'" when running elf/preloadtest, which we'd get otherwise. * elf/elf.h (PPC64_OPT_LOCALENTRY): Define. * sysdeps/alpha/dl-machine.h (elf_machine_fixup_plt): Add refsym and sym parameters.

Build divdi3 only for architecture that required it
As noted in [1], divdi3 object is only exported in a handful ABIs
(i386, m68k, powerpc32, s390-32, and ia64), however it is built
for all current architectures regardless.
This patch refact the make rules for this object to so only the
aforementioned architectures that actually require it builds it.
Also, to avoid internal PLT calls to the exported symbol from the
module, glibc uses an internal header (symbol-hacks.h) which is
unrequired (and in fact breaks the build for architectures that
intend to get symbol definitions from libgcc.a). The patch also
changes it to create its own header (divdi3-symbol-hacks.h) and
adjust the architectures that require it accordingly.
I checked the build/check (with run-built-tests=no) on the
following architectures (which I think must cover all supported
ABI/builds) using GCC 6.3:

S390: Clobber also r14 in TLS_LD, TLS_GD macros on 31bit.
This patch also clobbers r14 in TLS_LD, TLS_GD macros on 31bit.
This ensures that r14 isn't used to save and restore r12 while
r14 is clobbered by the bas-instruction.
As note:
r12 can't be added to clobber list as gcc would fail with:
error: PIC register clobbered by ‘12’ in ‘asm’
For 64bit this fix was already done in 2004 in the

Refactor long double information into bits/long-double.h.
Information about whether the ABI of long double is the same as that of double is split between bits/mathdef.h and bits/wordsize.h. When the ABIs are the same, bits/mathdef.h defines __NO_LONG_DOUBLE_MATH. In addition, in the case where the same glibc binary supports both -mlong-double-64 and -mlong-double-128, bits/wordsize.h defines __LONG_DOUBLE_MATH_OPTIONAL, along with __NO_LONG_DOUBLE_MATH if this particular compilation is with -mlong-double-64. As part of the refactoring I proposed in <https://sourceware.org/ml/libc-alpha/2016-11/msg00745.html>, this patch puts all that information in a single header, bits/long-double.h. It is included from sys/cdefs.h alongside the include of bits/wordsize.h, so other headers generally do not need to include bits/long-double.h directly. Previously, various bits/mathdef.h headers and bits/wordsize.h headers had this long double information (including implicitly in some bits/mathdef.h headers through not having the defines present in the default version). After the patch, it's all in six bits/long-double.h headers. Furthermore, most of those new headers are not architecture-specific. Architectures with optional long double all use the ldbl-opt sysdeps directory, either in the order (ldbl-64-128, ldbl-opt, ldbl-128) or (ldbl-128ibm, ldbl-opt). Thus a generic header for the case where long double = double, and headers in ldbl-128, ldbl-96 and ldbl-opt, suffices to cover every architecture except for cases where long double properties vary between different ABIs sharing a set of installed headers; fortunately all the ldbl-opt cases share a single compiler-predefined macro __LONG_DOUBLE_128__ that can be used to tell whether this compilation is -mlong-double-64 or -mlong-double-128. The two cases where a set of headers is shared between ABIs with different long double properties, MIPS (o32 has long double = double, other ABIs use ldbl-128) and SPARC (32-bit has optional long double, 64-bit has required long double), need their own bits/long-double.h headers. As with bits/wordsize.h, multiple-include protection for this header is generally implicit through the include guards on sys/cdefs.h, and multiple inclusion is harmless in any case. There is one subtlety: the header must not define __LONG_DOUBLE_MATH_OPTIONAL if __NO_LONG_DOUBLE_MATH was defined before its inclusion, because doing so breaks how sysdeps/ieee754/ldbl-opt/nldbl-compat.h defines __NO_LONG_DOUBLE_MATH itself before including system headers. Subject to keeping that working, it would be reasonable to move these macros from defined/undefined #ifdef to always-defined 1/0 #if semantics, but this patch does not attempt to do so, just rearranges where the macros are defined. After this patch, the only use of bits/mathdef.h is the alpha one for modifying complex function ABIs for old GCC. Thus, all versions of the header other than the default and alpha versions are removed, as is the include from math.h. Tested for x86_64 and x86.

s390: Refactor ifunc resolvers due to false debuginfo.
This patch adjusts the s390 specific ifunc helper macros in ifunc-resolve.h to use the common __ifunc macro, which uses gcc attribute ifunc to get rid of the false debuginfo. Therefore the redirection construct is applied where needed. Perhaps in future we can switch some of the internal symbols __GI_* from the fallback variant to the ifunc function. But this change is not straightforward due to a segmentation fault while linking libc.so with older binutils on s390. ChangeLog: [BZ #20478] * sysdeps/s390/multiarch/ifunc-resolve.h (s390_vx_libc_ifunc2, s390_libc_ifunc): Use __ifunc from libc-symbols.h to create ifunc symbols.

S390: Do not clobber r13 with memcpy on 31bit with copies >1MB.
If the default memcpy variant is called with a length of >1MB on 31bit,
r13 is clobbered as the algorithm is switching to mvcle. The mvcle code
returns without restoring r13. All other cases are restoring r13.
If memcpy is called from outside libc the ifunc resolver will only select
this variant if running on machines older than z10.
Otherwise or if memcpy is called from inside libc, this default memcpy
variant is called.
The testcase timezone/tst-tzset is triggering this issue in some combinations
of gcc versions and optimization levels.

S390: Use DT_JUMPREL in prelink undo code.
On s390, the current prelink undo code in elf_machine_lazy_rel() has the requirement, that the plt stubs use the first got slots after the 3 reserved ones. In case of undoing prelink, the plt got slots are reset to the correct addresses whithin the corresponding plt-stub. Therefore the address is calculated by the address of the first plt-stub-address which was written by prelink (see l->l_mach.plt) to got[1] and index of current relocation multiplied with 32 (=size of one plt slot). The index was calculated with ¤t-got-slot - &got[3]. This patch removes the requirement, that the plt-got-slots are starting at got[3]. The index is now calculated with ¤t-reloc - &reloc[0]. The first struct Elf64_Rela is stored at DT_JMPREL. This patch is needed to prepare for partial relro support. Ulrich Weigand suggested this approach to use DT_JMPREL - Thanks. ChangeLog: * sysdeps/s390/linkmap.h (struct link_map_machine): Remove member gotplt and add member jmprel. * sysdeps/s390/s390-32/dl-machine.h (elf_machine_runtime_setup): Setup member jmprel with DT_JMPREL instead of gotplt with &got[3]. (elf_machine_lazy_rel): Calculate address with reloc and jmprel. * sysdeps/s390/s390-64/dl-machine.h: Likewise. |

S390: Implement mempcpy with help of memcpy. [BZ #19765]
There exist optimized memcpy functions on s390, but no optimized mempcpy. This patch adds mempcpy entry points in memcpy.S files, which use the memcpy implementation. Now mempcpy itself is also an IFUNC function as memcpy is and the variants are listed in ifunc-impl-list.c. The s390 string.h does not define _HAVE_STRING_ARCH_mempcpy. Instead mempcpy string/string.h inlines memcpy() + n. If n is constant and small enough, GCC emits instructions like mvi or mvc and avoids the function call to memcpy. If n is not constant, then memcpy is called and n is added afterwards. If _HAVE_STRING_ARCH_mempcpy would be defined, mempcpy would be called in every case. According to PR70140 "Inefficient expansion of __builtin_mempcpy" (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70140) GCC should handle a call to mempcpy in the same way as memcpy. Then either the mempcpy macro in string/string.h has to be removed or _HAVE_STRING_ARCH_mempcpy has to be defined for S390. ChangeLog: [BZ #19765] * sysdeps/s390/mempcpy.S: New File. * sysdeps/s390/multiarch/mempcpy.c: Likewise. * sysdeps/s390/multiarch/Makefile (sysdep_routines): Add mempcpy. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add mempcpy variants. * sysdeps/s390/s390-32/memcpy.S: Add mempcpy entry point.

S390: Do not call memcpy, memcmp, memset within libc.so via ifunc-plt.
On s390, the memcpy, memcmp, memset functions are IFUNC symbols, which are created with s390_libc_ifunc-macro. This macro creates a __GI_ symbol which is set to the ifunced symbol. Thus calls within libc.so to e.g. memcpy result in a call to *ABS*+0x954c0@plt stub and afterwards to the resolved memcpy-ifunc-variant. This patch sets the __GI_ symbol to the default-ifunc-variant to avoid the plt call. The __GI_ symbols are now created at the default variant of ifunced function. ChangeLog: * sysdeps/s390/multiarch/ifunc-resolve.h (s390_libc_ifunc): Remove __GI_ symbol. * sysdeps/s390/s390-32/multiarch/memcmp-s390.S: Add __GI_memcmp symbol. * sysdeps/s390/s390-64/multiarch/memcmp-s390x.S: Likewise. * sysdeps/s390/s390-32/multiarch/memcpy-s390.S: Add __GI_memcpy symbol. * sysdeps/s390/s390-64/multiarch/memcpy-s390x.S: Likewise. * sysdeps/s390/s390-32/multiarch/memset-s390.S: Add __GI_memset symbol. * sysdeps/s390/s390-64/multiarch/memset-s390x.S: Likewise. |

S390: Use mvcle for copies > 1MB on 32bit with default memcpy variant.
If more than 255 bytes should be copied, the algorithm jumps away. Before this patch, it jumps to the mvc-loop (.L_G5_12). Now it jumps first to the "> 1MB" check, which jumps away to __memcpy_mvcle. Otherwise, the mvc-loop (.L_G5_12) copies the bytes. ChangeLog: * sysdeps/s390/s390-32/memcpy.S (memcpy): Jump to 1MB check before executing mvc-loop. |

S390: Use fPIC to avoid R_390_GOT12 relocation in gcrt1.o.
if glibc is build with -march=z900 | -march=z990, the startup file gcrt1.o (used if you link with gcc -pg) contains R_390_GOT12 | R_390_GOT20 relocations. Thus, an entry in the GOT can be addressed relative to the GOT pointer with a 12 | 20 bit displacement value. The startup files should not contain R_390_GOT12, R_390_GOT20 relocations, but R_390_GOTENT ones. This patch removes the overrides of pic-ccflag and the default pic-ccflag = -fPIC in Makeconfig is used instead to get the R_390_GOTENT relocations in gcrt1.o. ChangeLog: * sysdeps/s390/s390-32/Makefile (pic-ccflag): Remove. * sysdeps/s390/s390-64/Makefile: Likewise. |

S390: Extend structs La_s390_regs / La_s390_retval with vector-registers.
Starting with z13, vector registers can also occur as argument registers. Thus the passed input/output register structs for la_s390_[32|64]_gnu_plt[enter|exit] functions should reflect those new registers. This patch extends these structs La_s390_regs and La_s390_retval and adjusts _dl_runtime_profile() to handle those fields in case of running on a z13 machine. ChangeLog: * sysdeps/s390/bits/link.h: (La_s390_vr) New typedef. (La_s390_32_regs): Append vector register lr_v24-lr_v31. (La_s390_64_regs): Likewise.

S390: Save and restore fprs/vrs while resolving symbols.
On s390, no fpr/vrs were saved while resolving a symbol via _dl_runtime_resolve/_dl_runtime_profile. According to the abi, the fpr-arguments are defined as call clobbered. In leaf-functions, gcc 4.9 and newer can use fprs for saving/restoring gprs instead of saving them to the stack. If gcc do this in one of the resolver-functions, then the floating point arguments of a library-function are invalid for the first library-function-call. Thus, this patch saves/restores the fprs around the resolving code. The same could occur for vector registers. Furthermore an ifunc-resolver could also clobber the vector/floating point argument registers. Thus this patch provides the further variants _dl_runtime_resolve_vx/ _dl_runtime_profile_vx, which are used if the kernel claims, that we run on a machine with vector registers. Furthermore, if _dl_runtime_profile calls _dl_call_pltexit, the pointers to inregs-/outregs-structs were setup invalid. Now they point to the correct location in the stack-frame. Before branching back to the caller, the return values are now restored instead of containing the return values of the _dl_call_pltexit() call. On s390-32, an endless loop occurs if _dl_call_pltexit() should be called. Now, this code-path branches to this function instead of just after the preceding basr-instruction. ChangeLog: * sysdeps/s390/s390-32/dl-trampoline.S: Include dl-trampoline.h twice to create a non-vector/vector version for _dl_runtime_resolve and _dl_runtime_profile. Move implementation to ... * sysdeps/s390/s390-32/dl-trampoline.h: ... here. (_dl_runtime_resolve) Save and restore fpr/vrs.

Move implementation to ... * sysdeps/s390/s390-64/dl-trampoline.h: ... here. (_dl_runtime_resolve) Save and restore fpr/vrs. (_dl_runtime_profile) Save and restore vrs and fix some issues * sysdeps/s390/s390-64/dl-machine.h: (elf_machine_runtime_setup): Choose the correct resolver function if running on a machine with vx. |

S390: Clean setjmp, longjmp, getcontext symbols.
For each function setjmp, longjmp, getcontext, there exist a symbol <func> and a default/versioned symbol <func>@@GLIBC_2.x in the build obj-files. This is wrong because it should only exist an unversioned or a default-versioned symbol with the same name in an obj-file. Glibc can't be build with recent binutils. See the already fixed linker bug https://sourceware.org/bugzilla/show_bug.cgi?id=19073. Nevertheless, this patch cleans this up. Furthermore the BSD entry points setjmp, _setjmp were marked as weak, but should be strong as on other architectures. (see https://sourceware.org/ml/libc-alpha/2014-07/msg00568.html for an older discussion with Andreas Schwab) Some whitespace issues are corrected in sysdeps/s390/s390-64/setjmp.S, too. But there is no change in the assembler code. ChangeLog: * sysdeps/s390/longjmp.c (longjmp, _longjmp, siglongjmp): Don't create weak aliases, because versioned symbols are created later. * sysdeps/s390/s390-32/setjmp.S (setjmp, _setjmp): Remove weak and rename to an unique name in SHARED case due to existing versioned symbols. * sysdeps/s390/s390-64/setjmp.S: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/getcontext.S (getcontext): Create weak alias only in non SHARED case. * sysdeps/unix/sysv/linux/s390/s390-64/getcontext.S: Likewise. |

Move bits/libc-lock.h and bits/libc-lockP.h out of bits/ (bug 14912).
It was noted in <https://sourceware.org/ml/libc-alpha/2012-09/msg00305.html> that the bits/*.h naming scheme should only be used for installed headers. This patch renames bits/libc-lock.h to plain libc-lock.h and bits/libc-lockP.h to plain libc-lockP.h to follow that convention. Note that I don't know where libc-lockP.h comes from for Hurd (the Hurd libc-lock.h includes libc-lockP.h, but the only libc-lockP.h in the glibc source tree is for NPTL) - some unmerged patch? - but I updated the #include in the Hurd libc-lock.h anyway.

This patch provides optimized versions of strcmp and wcscmp with the z13 vector instructions.

S390: Refactor ifunc implementations and enable ifunc-test-framework.
On s390 all ifunc resolvers were implemented in multiarch/ifunc-resolve.c. The resulting single object files has undefined references to all ifunc-functions. This patch introduces one multiarch/<func>.c file for each of memcpy, memcmp and memset with the function specific ifunc resolver. The different function implementations are now implemented in multiarch/<func>-s390x.S (moved from multiarch/<func>.S). The new multiarch/ifunc-resolve.h file contains the ifunc-resolver macro and other helper-macros. They are merged and are now used in common for 32/64bit. Therefore the __<func>_g5/__<func>_z900 functions were renamed to __<func>_default. This patch also enables testing the ifunc implementations by implementing the function __libc_ifunc_impl_list. It uses the helper-macros of ifunc-resolve.h. ChangeLog: * sysdeps/s390/s390-32/multiarch/Makefile (sysdep_routines): Remove ifunc-resolve, add memset-s390, memcpy-s390, memcmp-s390. * sysdeps/s390/s390-32/multiarch/ifunc-resolve.c: Delete File. * sysdeps/s390/s390-32/multiarch/memcmp.S: Move to ... * sysdeps/s390/s390-32/multiarch/memcmp-s390.S: ... here.

Fix stack alignment when loader is invoked directly
The s390 ABI requires the stack pointer to be aligned at 8-bytes. When a program is invoked as an argument to the dynamic linker, _dl_start_user adjusts the stack to remove the dynamic linker arguments so that the program sees only its name and arguments. This may result in the stack being misaligned since each argument shift is only a word and not a double-word. This is now fixed shifting argv and envp down instead of shifting argc up and reclaiming the stack. This requires _dl_argv to be adjusted and hence, is no longer relro. |

Don't use INTDEF/INTUSE with _dl_init (bug 14132).
Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this patch eliminates its use for _dl_init. Since _dl_init was already declared with hidden visibility, creating a second hidden alias for it was completely pointless, so this patch replaces all uses of _dl_init_internal with plain _dl_init instead of using hidden_proto / hidden_def (which are only needed when you want a hidden alias for a non-hidden symbol; it's quite possible there are cases where they are used but don't need to be because the symbol in question is not part of the public ABI and is only used within a single library, so using attributes_hidden instead would suffice). Tested for x86_64 that installed stripped shared libraries are unchanged by the patch.
