Log message:
2003-08-30 Richard Earnshaw <rearnsha@arm.com>
Nicolas Pitre <nico@cam.org>
* arm/lib1funcs.asm (RETCOND): Delete.
(RETLDM): New assembler macro. Use it for returning with ldm/ldr.
(ARM_LDIV0, THUMB_LDIV0): Collapse multiple definitions.
(__ARM_ARCH__): Move here from ieee754-?f.S.
(RET, RETc): Clean up definitions.
(DIV_FUNC_END): Renamed from FUNC_END. All uses changed.
(FUNC_END): New macro that marks the end of any function.
(ARM_FUNC_START): New macro that allows an assembler routine to be
implemented in ARM code even if a Thumb-only build.
Unconditionally include ieee754-?f.S.
* arm/ieee754-df.S: Delete macros moved to lib1funcs.asm.
Mark ends of functions.
Split into separate conditionally-compiled units.
Use RETLDM to return from routines.
* arm/ieee754-sf.S: Similarly.
* t-arm-elf (LIB1ASMFUNCS): Remove _ieee754_dp and _ieee754_sp.
Add _negdf2 _addsubdf3 _muldivdf3 _cmpdf2 _unorddf2 _fixdfsi
_truncdfsf2 _negsf2 _addsubsf3 _muldivsf3 _cmpsf2 _unordsf2
_fixsfsi and _fixunssfsi.
* arm/ieee754-df.S (__muldf3): Fix bug when result of a
multiplication underflows to zero.
(__adddf3): Fix bug when using VFP ordering on little-endian
processors.
(__fixdfsi): Use rrx to extract the carry into a register instead of
MRS instruction. Optimize later use of result.
* arm/ieee754-sf.S (__fixsfsi): Likewise.
(__fixunssfsi): Use a better sequence for handling negative-or-zero.
