* S/390: Do not raise inexact exception in lrint/lround. [BZ #19486]Stefan Liebler2016-01-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I get some math test-failures on s390 for float/double/ldouble for various lrint/lround functions like: lrint (0x1p64): Exception "Inexact" set lrint (-0x1p64): Exception "Inexact" set lround (0x1p64): Exception "Inexact" set lround (-0x1p64): Exception "Inexact" set ... GCC emits "convert to fixed" instructions for casting floating point values to integer values. These instructions raise invalid and inexact exceptions if the floating point value exceeds the integer type ranges. This patch enables the various FIX_DBL_LONG_CONVERT_OVERFLOW macros in order to avoid a cast from floating point to integer type and raise the invalid exception with feraiseexcept. The ldbl-128 rint/round functions are now using the same logic. ChangeLog: [BZ #19486] * sysdeps/s390/fix-fp-int-convert-overflow.h: New File. * sysdeps/generic/fix-fp-int-convert-overflow.h (FIX_LDBL_LONG_CONVERT_OVERFLOW, FIX_LDBL_LLONG_CONVERT_OVERFLOW): New define. * sysdeps/arm/fix-fp-int-convert-overflow.h: Likewise. * sysdeps/mips/mips32/fpu/fix-fp-int-convert-overflow.h: Likewise. * sysdeps/ieee754/ldbl-128/s_lrintl.c (__lrintl): Avoid conversions to long int where inexact exceptions could be raised. * sysdeps/ieee754/ldbl-128/s_lroundl.c (__lroundl): Likewise. * sysdeps/ieee754/ldbl-128/s_llrintl.c (__llrintl): Avoid conversions to long long int where inexact exceptions could be raised. * sysdeps/ieee754/ldbl-128/s_llroundl.c (__llroundl): Likewise.

* Fix lrint, llrint, lround, llround missing exceptions for MIPS (bug 16399).Joseph Myers2015-10-091-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For 32-bit MIPS and some other systems, various of the lrint, llrint, lround, llround functions can be missing exceptions on overflow because casts do not (in current GCC) result in the proper exceptions. In the MIPS case there are two problems here: MIPS I code generation uses an assembler macro that doesn't raise exceptions, while the libgcc conversions of floating-point values to long long also do not raise "invalid" on all overflow cases (and can raise spurious "inexact"). This patch adds support in the generic code (only the functions for which this problem has actually been seen) for forcing the "invalid" exception in the problem cases, and enables that support for the affected MIPS cases. Tested for MIPS; also tested for x86_64 and x86 that installed stripped shared libraries are unchanged by this patch. [BZ #16399] * sysdeps/generic/fix-fp-int-convert-overflow.h: New file. * sysdeps/ieee754/dbl-64/s_llrint.c: Include <fenv.h>, <limits.h> and <fix-fp-int-convert-overflow.h>.

* Fix mips16 __fpu_control static linking (bug 18397).Joseph Myers2015-05-112-1/+4
| | | | | | | | | | | | | | | | | | | | | Programs are supposed to be able to define the __fpu_control variable, overriding the library's version to cause the floating-point control word to be set to the chosen value at startup. This is broken for mips16 for static linking because the library's __fpu_control variable is in the same object file as the helper functions used by fpu_control.h for mips16, so test-fpucw-ieee-static fails to link with multiple definitions of __fpu_control. This patch fixes this by putting the helpers in a separate file rather than overriding fpu_control.c. Tested for mips16 that this fixes the link failure and the ABI tests still pass. [BZ #18397] * sysdeps/mips/mips32/fpu/fpu_control.c: Move to .... * sysdeps/mips/mips32/fpu/fpucw-helpers.c: ... here. Include <fpu_control.h> instead of <math/fpu_control.c>. * sysdeps/mips/mips32/fpu/Makefile: New file.

* Move mips from ports to libc.Joseph Myers2014-02-104-0/+41
I've moved the MIPS port from ports to the main sysdeps hierarchy. Beyond the README update, the move of the files was simply git mv ports/sysdeps/mips sysdeps/mips git mv ports/sysdeps/unix/mips sysdeps/unix/mips git mv ports/sysdeps/unix/sysv/linux/mips sysdeps/unix/sysv/linux/mips and in addition to the ChangeLog entries here, I put a note at the top of ports/ChangeLog.mips similar to those in other files. Tested that disassembly of installed shared libraries for mips is the same before and after this patch (except for ld.so where paths in assertions are involved, as for arm). * sysdeps/mips: Move directory from ports/sysdeps/mips. * sysdeps/unix/mips: Move directory from ports/sysdeps/unix/mips. * sysdeps/unix/sysv/linux/mips: Move directory from ports/sysdeps/unix/sysv/linux/mips. * README: Update listing for mips-*-linux-gnu and mips64-*-linux-gnu. * sysdeps/mips: Move directory to ../sysdeps/mips. * sysdeps/unix/mips: Move directory to ../sysdeps/unix/mips. * sysdeps/unix/sysv/linux/mips: Move directory to ../sysdeps/unix/sysv/linux/mips.
