Move tilegx, tilepro, and linux-generic from ports to libc. I've moved the TILE-Gx and TILEPro ports to the main sysdeps hierarchy, along with the linux-generic ports infrastructure. Beyond the README update, the move was just git mv ports/sysdeps/tile sysdeps/tile git mv ports/sysdeps/unix/sysv/linux/tile \ sysdeps/unix/sysv/linux/tile git mv ports/sysdeps/unix/sysv/linux/generic \ sysdeps/unix/sysv/linux/generic I updated the relevant ChangeLogs along the lines of the ARM move in commit c6bfe5c4d75 and tested the 64-bit tilegx build to confirm that there were no changes in "objdump -dr" output in the shared objects.
2014-02-10 15:54:47 +00:00
This file describes changes to the TILE-Gx and TILEPro ports while they
were in the ports add-on directory. These ports are no longer part of
an add-on and so future changes to them should be listed in the top-level
ChangeLog file, not here.

BZ #15754: CVE-2013-4788 The pointer guard used for pointer mangling was not initialized for static applications resulting in the security feature being disabled. The pointer guard is now correctly initialized to a random value for static applications. Existing static applications need to be recompiled to take advantage of the fix. The test tst-ptrguard1-static and tst-ptrguard1 add regression coverage to ensure the pointer guards are sufficiently random and initialized to a default value.

Avoid crashing in LD_DEBUG when program name is unavailable Resolves: #15465 The program name may be unavailable if the user application tampers with argc and argv[].

tile: improve detection for missing -mcmodel=large support The existing test avoided passing -mcmodel=large if the compiler didn't support it. However, we need to test not just the compiler support, but also the toolchain (as and ld) support, so make the test more complete. In addition, we have to avoid using the hwN_plt() assembly operators if that support is missing, so guard the uses with #ifdef NO_PLT_PCREL. This allows us to properly build glibc with the current community binutils, which doesn't yet have the PC-relative PLT operator support. The -mcmodel=large support is in gcc 4.8, but the toolchain support won't be present in the community until binutils 2.24.

C++11 thread_local destructors support This feature is specifically for the C++ compiler to offload calling thread_local object destructors on thread program exit, to glibc. This is to overcome the possible complication of destructors of thread_local objects getting called after the DSO in which they're defined is unloaded by the dynamic linker. The DSO is marked as 'unloadable' if it has a constructed thread_local object and marked as 'unloadable' again when all the constructed thread_local objects defined in it are destroyed.

tile: support very large shared objects With gcc 4.8 tilegx has support for -mcmodel=large, to tolerate very large shared objects. This option changes the compiler output to not include direct jump instructions, which have a range of only 2^30, i.e +/- 512MB. Instead the compiler marshalls the target PCs into registers and then uses jump- or call-to-register instructions. For glibc, the upshot is that we need to arrange for a few functions to tolerate the possibility of a large range between the PC and the target. In particular, the crti.S and start.S code needs to be able to reach from .init to the PLT, as does gmon-start.c. The elf-init.c code has the reverse problem, needing to call from libc_nonshared.a (linked at the end of shared objects) back to the _init section at the beginning. No other functions in *_nonshared.a need to be built this way, as they only call the PLT (or potentially each other), but all of that code is linked at the very end of the shared object. We don't build the standard -static archives with this option as the performance cost is high enough and the use case is rare enough that it doesn't seem worthwhile. Instead, we would encourage developers who need the -static model with huge executables to build a private copy of glibc and configure it with -mcmodel=large. Note that libc.so et al don't need any changes; the only changes are for code that is statically linked into user code built with -mcmodel=large. For the assembly code, I just rewrote it so that it unconditionally uses the large model. To be able to pass -mcmodel=large to csu/elf-init.c and csu/gmon-start.c, I need to check to see if the compiler supports that flag, since gcc 4.7 doesn't; I added the support by creating a small Makefile fragment that just runs the compiler to check.

Optimize tile (mostly tilegx) memcpy and memmove performance. - Override <memcopy.h> so we use full 8-byte word copies on tilegx32 for memmove, then use op_t in memcpy instead of the previous locally-defined word_t just to avoid proliferating identical types. - Fix bug in memcpy prefetch that caused us to never prefetch past the first cache line. - Optimize misaligned memcpy by inlining _wordcopy_fwd_dest_aligned instead of just doing a dumb word-at-a-time copy. - Make memcpy safe for forward copies by doing all the loads from a given cache line prior to doing a wh64 (cache line zero-fill) on the destination. Remove now-redundant src == dst check. - Copy and optimize the generic wordcopy.c routines to use the tile "double align" instruction instead of the MERGE macro; to avoid offset addressing mode (which tile doesn't have) by rewriting the pointer math to load and store with a zero index; and to use post-increment addresses in the inner loops to improve scheduling.

tile: improve simulator notification for relative paths in dlopen Normally, the simulator is notified of absolute pathnames by the _dl_load_hook hook. However, when a relative pathname is used, the simulator may not know that the relative path matches a path that it could figure out in the file system that it has access to. Instead we provide a simplified version of the realpath function so we can pass a plausible absolute pathname to the simulator. Since we're now doing more work at object load time, we also add a guard so we do no work at all if we're not running on the simulator.

Optimize tile (mostly tilegx) memcpy and memmove performance. - Override <memcopy.h> so we use full 8-byte word copies on tilegx32 for memmove, then use op_t in memcpy instead of the previous locally-defined word_t just to avoid proliferating identical types. - Fix bug in memcpy prefetch that caused us to never prefetch past the first cache line. - Optimize misaligned memcpy by inlining _wordcopy_fwd_dest_aligned instead of just doing a dumb word-at-a-time copy. - Make memcpy safe for forward copies by doing all the loads from a given cache line prior to doing a wh64 (cache line zero-fill) on the destination. Remove now-redundant src == dst check. - Copy and optimize the generic wordcopy.c routines to use the tile "double align" instruction instead of the MERGE macro; to avoid offset addressing mode (which tile doesn't have) by rewriting the pointer math to load and store with a zero index; and to use post-increment addresses in the inner loops to improve scheduling.

Invoke DL_AFTER_LOAD if defined This hook is useful for any arch-specific functionality that should be done on loaded objects. For the tile architecture, the hook is already provided (though we switch to using the new macro name with this commit) and implements a simulator notifier so that the simulator can load Elf symbols to match the object and generate better error messages for PC's. Also, remove a spurious definition of DL_UNMAP in dl-runtime.c

tile: fix type of prfpregset_t in <sys/procfs.h> The previous dummy definition (as type int) was fine in general, since tile doesn't have floating-point registers, but it confused gdb's configure, leading to later compile errors. This change also makes prfpregset_t parallel to prgregset_t, which seems like generally the right thing regardless of the non-existence of the actual registers :-)

tile: align stack for tilegx32 Previously we weren't re-aligning the stack pointer during the call to _dl_init(), so for tilegx32 and an odd value in _dl_skip_args and kernel unaligned access fixups disabled, we would die with SIGBUS. We now handle this case properly by aligning before calling _dl_init().
2012-05-14 19:03:46 +00:00
* sysdeps/tile/dl-start.S: Align stack for tilegx32.
tile: add include <features.h> to <sys/dataplane.h> We were using __BEGIN_DECLS without <features.h> and it just happened to mostly work, but of course we should include it here.
2012-05-11 22:10:00 +00:00
2012-05-12 Chris Metcalf <cmetcalf@tilera.com>
* sysdeps/unix/sysv/linux/tile/sys/dataplane.h: Add <features.h>.
tile: fix bug in CFI definitions for clone.S We were missing a critical cfi_def_cfa_offset call in .Lthread_start which caused backtracing to get badly confused for threads.
2012-05-11 22:08:03 +00:00
* sysdeps/unix/sysv/linux/tile/nptl/clone.S: Add missing CFI.
tile: fix broken TLS_GD macros These still corresponded to an older version of the TLS code in the compiler. Now they match the code in gcc 4.7.
2012-05-11 22:06:42 +00:00
* sysdeps/tile/tls-macros.h: Fix buggy TLS_GD, etc., macros.
tilegx: small performance fix for string routines We were multiplying a byte by 0x0101010101010101ULL to create a constant for SIMD ops, but the compiler isn't good at optimizing this case (the fact that one operand is a byte is lost by the time it would be possible to do the optimization). So instead we add a helper routine that explicitly uses SIMD ops to create the constant.
2012-05-11 22:03:58 +00:00
* sysdeps/tile/tilegx/memchr.c: Use new copy_byte() function
to efficiently generate a large constant for masking.
* sysdeps/tile/tilegx/memset.c: Likewise.
* sysdeps/tile/tilegx/rawmemchr.c: Likewise.
* sysdeps/tile/tilegx/strchr.c: Likewise.
* sysdeps/tile/tilegx/strchrnul.c: Likewise.
* sysdeps/tile/tilegx/strrchr.c: Likewise.
* sysdeps/tile/tilegx/string-endian.h (copy_byte): New function.
tile: allow memcpy(p, p, n) without corrupting memory at "p" Although this is not required by the definition of memcpy(), in practice this sort of thing does happen, and it's easy to make the code robust by doing nothing in this case. (Since structure copy causes the compiler to emit a memcpy, in the case where the target structure is the same as the destination, we were seeing corruption.)
2012-05-11 21:59:23 +00:00
* sysdeps/tile/tilegx/memcpy.c: Allow memcpy(p, p, n)
without corrupting memory at "p".
tile: avoid using _LP64 The convention is to use __WORDSIZE everywhere. I happened to notice that we weren't doing this in __tls_get_addr.S.
2012-05-11 20:53:19 +00:00
* sysdeps/tile/__tls_get_addr.S: Use __WORDSIZE, not _LP64.
tile: support stackguard-macros.h header
2012-05-11 20:11:04 +00:00
* sysdeps/tile/stackguard-macros.h: New file.
* sysdeps/tile/elf/stackguard-macros.h: New stub include file.
tile: remove stale #define of ELF_MACHINE_PLTREL_OVERLAP
2012-05-11 19:42:04 +00:00
* sysdeps/tile/Makefile (ELF_MACHINE_PLTREL_OVERLAP):
Remove variable no longer used by core.
tile: update pthread_attr_t and struct siginfo names This adds a tag to the pthread_attr_t underlying type so we can forward-declare it, and removes the siginfo_t type, to match changes in the main tree.
2012-05-11 18:42:46 +00:00
* sysdeps/unix/sysv/linux/tile/bits/siginfo.h: Don't name
siginfo_t struct. Add forward declaration of pthread_attr_t and
use it in sigevent.
* sysdeps/unix/sysv/linux/tile/nptl/bits/pthreadtypes.h: Name
pthread_attr_t union.
tile: Remove elf/ and create crti.S/crtn.S This patches fixes up the tile startup files, moving elf/start.S up a directory level and implementing the required crti.S and crtn.S files based on the old initfini.c compiler output (hand-optimized to bum a couple of cycles).
2012-05-11 18:27:57 +00:00
* sysdeps/tile/crti.S: New file, based on compiler output
for sysdeps/generic/initfini.c.
* sysdeps/tile/crtn.S: Likewise.
* sysdeps/tile/Makefile (CFLAGS-initfini.s): Remove variable.
* sysdeps/unix/sysv/linux/tile/nptl/Makefile

* sysdeps/tile/elf/start.S: Moved to ...
* sysdeps/tile/start.S: ...here.
tile: update _itoa.h include path Common code moved _itoa.h necessitating a change in the #include path. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-04-15 01:10:30 +00:00
2012-04-15 Mike Frysinger <vapier@gentoo.org>
* sysdeps/unix/sysv/linux/tile/tilegx/register-dump.h: Include
<_itoa.h> instead of <stdio-common/_itoa.h>.
* sysdeps/unix/sysv/linux/tile/tilepro/register-dump.h: Likewise.
Use include_next to chain math_private.h headers.
2012-03-10 00:28:42 +00:00
2012-03-09 Richard Henderson <rth@twiddle.net>

2012-03-09 Paul Eggert <eggert@cs.ucla.edu>
[BZ #13673]

tile: use const instead of __const.
2012-01-31 16:46:09 +00:00
2012-01-31 Chris Metcalf <cmetcalf@tilera.com>
* sysdeps/tile/bits/fenv.h: Use const instead of __const.
* sysdeps/unix/sysv/linux/tile/sys/cachectl.h: Likewise.
tile: use <feedback.h> instead of <feedback-asm.h> in sysdep.h.
2012-01-31 16:26:00 +00:00
2012-01-31 Chris Metcalf <cmetcalf@tilera.com>
* sysdeps/tile/sysdep.h: Use <feedback.h> not <feedback-asm.h>
to reflect change from gcc community giveback.
tile: Ignore feraiseexcept() internally.
2012-01-31 13:59:30 +00:00
2012-01-31 Chris Metcalf <cmetcalf@tilera.com>
* sysdeps/tile/math_private.h: Ignore feraiseexcept() internally.
Don't check HAVE_ELF or NO_UNDERSCORES in sysdeps/tile/sysdep.h.
2012-01-30 17:43:25 +00:00
2012-01-30 Chris Metcalf <cmetcalf@tilera.com>
* sysdeps/tile/sysdep.h: Don't check HAVE_ELF or NO_UNDERSCORES.

2012-01-07 16:53:16 +00:00
2012-01-07 Joseph Myers <joseph@codesourcery.com>
* sysdeps/tile/backtrace.c: Use x86_64 version of backtrace.c.
Add sysdeps/tile, sysdeps/unix/sysv/linux/tile. Changes are tracked in ChangeLog.tile. Also add data/c++-types-tile-linux-gnu.data.
