soft-fp: Add _FP_TO_INT_ROUND.
Continuing the series of patches adding soft-fp features from the kernel version of soft-fp to glibc so that glibc's version is able to replace the old fork of soft-fp in the kernel, this patch adds the last major such feature: _FP_TO_INT_ROUND, converting a floating-point number to an integer with rounding according to the current rounding direction (as opposed to truncating towards zero, which _FP_TO_INT does). The general structure of the implementation follows that of _FP_TO_INT, but of course is more complicated. As with glibc's _FP_TO_INT it works with raw input (the kernel versions of these macros predate the conversion of _FP_TO_INT and many other macros to raw or semi-raw input). I have not tried to work out what bugs there might be in the kernel version that this might fix; it's a from-scratch implementation based on _FP_TO_INT. Tested for powerpc (soft-float) that there is no change to the installed shared libraries; also tested with the libm tests with lrint / lrintf / llrint / llrintf made to use _FP_TO_INT_ROUND, to provide some test of the functionality. As we don't have benchmarks for those functions, I haven't actually included the soft-fp versions of them, although I expect them to be faster than the existing code (given that the existing code involves adding and subtracting numbers such as 0x1p52 to achieve the desired rounding, which is not particularly efficient when the underlying floating point is software floating point). 2014-11-04 Joseph Myers <joseph@codesourcery.com> * soft-fp/op-common.h (_FP_TO_INT_ROUND): New macro. * soft-fp/double.h [_FP_W_TYPE_SIZE < 64] (FP_TO_INT_ROUND_D): New macro.

soft-fp: Use parentheses around macro arguments.
This patch cleans up the soft-fp code to use parentheses around macro arguments (where possible; many macro arguments are identifiers used with ## rather than arbitrary expressions, so cannot be put in parentheses). (I'm not aware of any bugs caused by the lack of parentheses, but this is generally good practice. The patch is not exhaustive regarding internal macros where the arguments always come directly from the mantissa of a floating-point number, although probably those should be cleaned up in this regard as well.) Tested for powerpc-nofpu that the installed shared libraries are unchanged by this patch. * soft-fp/double.h [_FP_W_TYPE_SIZE < 64] (FP_UNPACK_RAW_D): Use parentheses around macro arguments.

soft-fp: Support rsigned == 2 in _FP_TO_INT.
Continuing the addition of soft-fp features in the Linux kernel version, this patch adds _FP_TO_INT support for rsigned == 2 (reduce overflowing results modulo 2^rsize to fit in the destination, used for alpha emulation). The kernel version is buggy; it can left shift by a negative amount when right shifting is required in an overflow case (the kernel version also has other bugs fixed long ago in glibc; at least, spurious exceptions converting to the most negative integer). This version avoids that by handling overflow (other than to 0) for rsigned == 2 along with the normal non-overflow case, which already properly determines the direction in which to shift. Tested for powerpc-nofpu. Some functions get slightly bigger and some get slightly smaller, no doubt as a result of the change to where in the macro "inexact" is raised, but I don't think those changes are significant. Also tested for powerpc-nofpu with the relevant __fix* functions changed to use rsigned == 2 (which is after all just as valid as rsigned == 1 in IEEE terms), including verifying the results and exceptions for various cases of conversions. With these seven patches, the one remaining feature to add for the soft-fp code to have all the features of the kernel version is _FP_TO_INT_ROUND. * soft-fp/op-common.h (_FP_TO_INT): Handle rsigned == 2. |

soft-fp: Support more precise "invalid" exceptions.
As previously discussed <https://sourceware.org/ml/libc-alpha/2013-10/msg00345.html>, it would be desirable to be able to use the same version of the soft-fp code in the Linux kernel as well as in glibc and libgcc (instead of an old version in the kernel that's missing ten years of bug fixes, performance improvements and new features), and to that end it is useful to add to glibc's copy features in the kernel's copy, even when they are not directly useful in glibc. To that end, this patch adds one of those features: support for more precise "invalid" exceptions describing the particular kind of invalid operation. These are relevant for powerpc emulation, and are also as described in IEEE 754-2008 as sub-exceptions. The set of sub-exceptions here is the union of those supported on powerpc and those from IEEE 754-2008 (the former adds a distinction between 0/0 and Inf/Inf; the latter adds a distinction between Inf*0 from multiplication and the same from fma). This includes sub-exceptions for sqrt, conversions to integer and comparisons that are not supported in the kernel; I see no obvious reason for these being missing from the kernel support, given that they are supported on powerpc so accurate powerpc emulation should generate them. Tested for powerpc-nofpu that the disassembly of installed shared libraries is unchanged by this patch. * soft-fp/soft-fp.h (FP_EX_INVALID_SNAN): New macro. (FP_EX_INVALID_IMZ): Likewise.

soft-fp: Add FP_DENORM_ZERO.
Continuing the addition of soft-fp features used in the Linux kernel, this patch adds soft-fp support for FP_DENORM_ZERO (flushing input subnormal operands to zero of the same sign). There are some differences from the kernel version. In the kernel, the "inexact" exception is set when flushing to zero. This does not appear to match the documented semantics for either of the architectures (alpha and sh) for which the kernel uses FP_DENORM_ZERO, so this patch does not set "inexact" in this case. More operations now use raw or semi-raw unpacking for optimization than did in the ten-year-old soft-fp version in the kernel, so checks of FP_DENORM_ZERO are inserted in those operations. They are also inserted for comparisons (which already used raw unpacking in the old version) as I believe that's the correct thing to do when input subnormals are flushed to zero. They are *not* inserted for _FP_NEG. (If any processors do flush input subnormals to zero for negation, or otherwise vary from the rules implemented when FP_DENORM_ZERO is set, further macros for sfp-machine.h to control this may need to be added.) Although the addition for comparisons will cause FP_EX_DENORM to be set in this case, it still won't be set for comparisons involving subnormals when not flushed to zero. It's quite possible that accurate emulation of processors that have such an exception for subnormal operands will require further changes relating to when FP_EX_DENORM is set (in general, the support for things defined by IEEE should be considered more reliable and mature than the support for things outside the scope of IEEE floating point). Although some processors also have a mode for abrupt underflow - producing zeroes instead of output subnormals - there is no such mode in the kernel's soft-fp, so no such mode is added to glibc's soft-fp (although it could be if someone wanted to emulate such processor support). Tested for powerpc-nofpu that the disassembly of installed shared libraries is unchanged by this patch. * soft-fp/soft-fp.h (FP_DENORM_ZERO): New macro. * soft-fp/op-common.h (_FP_UNPACK_CANONICAL): Check FP_DENORM_ZERO.

soft-fp: Fix _FP_TO_INT latent bug in overflow handling.
This patch fixes a latent bug in _FP_TO_INT regarding handling of arguments with maximum exponent (infinities and NaNs). If the maximum exponent is below that calculated as an overflow threshold, such values would incorrectly be treated as normal values for the purposes of the conversion. This could not occur for any of the conversions actually occurring in glibc, libgcc or the Linux kernel (the maximum exponent for float is, just, big enough to ensure overflow for unsigned __int128), but would apply if soft-fp were used for IEEE binary16. Appropriate checks are inserted to ensure that the maximum exponent is always treated as an overflowing exponent, and never as a normal one. Tested for powerpc-nofpu that the disassembly of installed shared libraries is unchanged by this patch. * soft-fp/op-common.h (_FP_TO_INT): Ensure maximum exponent is treated as invalid conversion, not as normal exponent. |

soft-fp: Refactor exception handling for comparisons.
This patch refactors how soft-fp comparisons handle setting exceptions for NaN operands, so that exceptions are set through the FP_CMP macros rather than directly in the C files calling them. The _FP_CMP* and FP_CMP* macros gain an extra argument to specify when exceptions should be set, 0 for no exception setting (I'm not sure this is actually needed - at least it's not needed for IEEE operations in glibc / libgcc, but might be relevant in some cases for kernel use), 1 for exceptions only for signaling NaNs and 2 for exceptions for all NaNs. This argument is handled through _FP_CMP_CHECK_NAN, newly called by the _FP_CMP* macros when a NaN is encountered. Calls to these macros are updated, which eliminates all the existing checking and exception setting in soft-fp *.c files in glibc. Tested for powerpc-nofpu. (The __unord* functions have no code changes; the __eq* / __ge* / __le* functions get slightly larger, but I don't think that's significant.) * soft-fp/op-common.h (_FP_CMP_CHECK_NAN): New macro.

soft-fp: Make extensions of subnormals from XFmode to TFmode signal underflow if traps enabled.
This patch fixes a soft-fp corner case I previously noted in <https://sourceware.org/ml/libc-alpha/2013-10/msg00349.html>: when trapping on underflow is enabled, extensions of subnormals from XFmode to TFmode need to signal underflow because the result is tiny (but exact, so the underflow flag is not raised unless trapping is enabled). To avoid any excess initialization or tests for other cases of floating-point extensions, a new FP_INIT_TRAPPING_EXCEPTIONS is added that does the initialization required for this particular case (more than FP_INIT_EXCEPTIONS, less than FP_INIT_ROUNDMODE, in general), and FP_NO_EXACT_UNDERFLOW is added to stub out FP_TRAPPING_EXCEPTIONS tests for those cases of extensions where the test would be dead code, to avoid any uninitialized variable warnings. As the relevant case only applies in libgcc, not to any use of soft-fp in glibc, there is no bug report in Bugzilla and no non-default definitions of FP_INIT_TRAPPING_EXCEPTIONS are added by the patch. A testcase will be added to GCC as part of an update of soft-fp in libgcc once this patch is in libc. Tested for powerpc-nofpu that the disassembly of installed shared libraries is unchanged by this patch. Bootstrapped GCC with updated soft-fp with no regressions on x86_64-unknown-linux-gnu and verified that a test of the relevant case passes where it failed before. * soft-fp/op-common.h (FP_EXTEND): When a subnormal input produces a subnormal result, set the underflow exception if trapping on underflow is enabled. * soft-fp/soft-fp.h (FP_INIT_TRAPPING_EXCEPTIONS): New macro.

soft-fp: Correct _FP_TO_INT formatting.
This patch corrects some soft-fp formatting that failed to follow the GNU Coding Standards. Tested for powerpc-nofpu that the disassembly of installed shared libraries is unchanged by this patch. * soft-fp/op-common.h (_FP_TO_INT): Correct formatting. |

Rename soft-fp extended.h, op-common.h variables to avoid risk of shadowing.
In <https://sourceware.org/ml/libc-alpha/2013-06/msg00851.html>, I fixed a bug caused by multiple soft-fp macros using the same variable names, resulting in shadowing when one macro called another that used the same variable name, with an argument involving the variable in the outer macro. The fix was to rename the local variables so their names included the containing macro name, to ensure uniqueness. I noted then that this would make sense more systematically for all variables in any soft-fp macro. Since then, I've used such variable names in new soft-fp macros. This patch now converts existing macros in extended.h and op-common.h to use this convention. (op-[1248].h are intended to be converted separately.) (Name conflicts could arise for label names as well, but because those are function-scope in C any such conflict will give an immediate compile error rather than a subtle bug, so there's no need for preemptive renaming in that case.) Tested for powerpc32 (soft-float) and mips64 that this makes no change to the disassembly of installed shared libraries. * soft-fp/extended.h (FP_UNPACK_RAW_E): Rename local variables to include macro name. (FP_UNPACK_RAW_EP): Likewise. (FP_PACK_RAW_E): Likewise. (FP_PACK_RAW_EP): Likewise. * soft-fp/op-common.h (_FP_UNPACK_CANONICAL): Likewise. (_FP_ISSIGNAN): Likewise. (_FP_ADD_INTERNAL): Likewise.

soft-fp: support after-rounding tininess detection.
IEEE 754-2008 defines two ways in which tiny results can be detected, "before rounding" (based on the infinite-precision result) and "after rounding" (based on the result when rounded to normal precision as if the exponent range were unbounded). All binary operations on an architecture must use the same choice of how tininess is detected. soft-fp has so far implemented only before-rounding tininess detection. This patch adds support for after-rounding tininess detection. A new macro _FP_TININESS_AFTER_ROUNDING is added that sfp-machine.h must define (soft-fp is meant to be self-contained so the existing tininess.h files aren't used here, though the information going in sfp-machine.h has been taken from them). The soft-fp macros dealing with raising underflow exceptions then handle the cases where the choice matters specially, rounding a copy of the input to the appropriate precision to see if a value that's tiny before rounding isn't tiny after rounding. Tested for mips64 using GCC trunk (which now uses soft-fp on MIPS, so supporting exceptions and rounding modes for long double where not previously supported - this is the immediate motivation for doing this patch now) together with (a) a patch to sysdeps/mips/math-tests.h to enable exceptions / rounding modes tests for long double for GCC 4.9 and later, and (b) corresponding changes applied to libgcc's soft-fp and sfp-machine.h files. In the libgcc context this is also tested on x86_64 (also an after-rounding architecture) with testcases for __float128 that I intend to add to the GCC testsuite when updating soft-fp there. (To be clear: this patch does not fix any glibc bugs that were user-visible in past releases, since after-rounding architectures didn't use soft-fp in any affected case with support for floating-point exceptions - so there is no corresponding Bugzilla bug. Rather, it works together with the GCC changes to use soft-fp on MIPS to allow previously absent long double functionality to work properly, and allows soft-fp to be used in glibc on after-rounding architectures in cases where it couldn't previously be used.) * soft-fp/op-common.h (_FP_DECL): Mark exponent as possibly unused. (_FP_PACK_SEMIRAW): Determine tininess based on rounding shifted value if _FP_TININESS_AFTER_ROUNDING and unrounded value is in subnormal range. (_FP_PACK_CANONICAL): Determine tininess based on rounding to normal precision if _FP_TININESS_AFTER_ROUNDING and unrounded value has largest subnormal exponent. * soft-fp/soft-fp.h [FP_NO_EXCEPTIONS] (_FP_TININESS_AFTER_ROUNDING): Undefine and redefine to 0. * sysdeps/aarch64/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): New macro. * sysdeps/alpha/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/arm/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/mips/mips64/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/mips/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/powerpc/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/sh/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/sparc/sparc32/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/sparc/sparc64/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/tile/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. |

MIPS: soft-fp NaN representation corrections
[BZ #15442] This adds support for the inverse interpretation of the quiet bit of IEEE 754 floating-point NaN data that some processors use. This includes in particular MIPS architecture processors; the payload used for the canonical qNaN encoding is updated accordingly so as not to interfere with the quiet bit. |

soft-fp: Fix used without set warning in _FP_MUL and _FP_DIV
Seen in, e.g. ports/sysdeps/alpha/soft-fp/ots_mul.c. The problem here is we have a switch on the class of X*Y, followed by a switch on the class of R. The exponent field of R really is not set by the first switch for NaN outputs, because we know it's not going to be used. The compiler is not smart enough to see through this. By pulling the exponent computation out of the NORMAL*NORMAL path, we will not be pessimizing the most common case, while still providing an arbitrary value to satisfy the compiler. |
