switch arm, sh, and mips fenv asm from .sub system to .S files

2016-01-20T02:07:59+00:00

explicitly assemble all arm asm sources as UAL

2015-11-10T05:01:55+00:00

these files are all accepted as legacy arm syntax when producing arm
code, but legacy syntax cannot be used for producing thumb2 with
access to the full ISA. even after switching to UAL, some asm source
files contain instructions which are not valid in thumb mode, so these
will need to be addressed separately.

use vfp mnemonics instead of p10 coprocessor ones in armhf fenv asm

2015-11-05T23:14:39+00:00

mrc/mcr p10 coprocessor mnemonics are deprecated by some
toolchains.

declare fpu usage to the assembler in arm hard-float asm files

2015-10-19T06:05:58+00:00

Some armhf gcc toolchains (built with --with-float=hard but without
--with-fpu=vfp*) do not pass -mfpu=vfp to the assembler and then
binutils rejects the UAL mnemonics for VFP unless there is an .fpu vfp
directive in the asm source.

simplify armhf fesetenv

2015-02-08T18:13:09+00:00

armhf fesetenv implementation did a useless read of the fpscr.

fix fenv exception functions to mask their argument

2013-08-18T20:08:18+00:00

fesetround.c is a wrapper to do the arch independent argument
check (on archs where rounding mode is not stored in 2 bits
__fesetround still has to check its arguments)

on powerpc fe*except functions do not accept the extra invalid
flags of its fpscr register

the useless FENV_ACCESS pragma was removed from feupdateenv

support floating point environment (fenv) on armhf (hard float) subarchs

2013-08-16T16:30:37+00:00

patch by nsz. I've tested it on an armhf machine and it seems to be
working correctly.
