e010b5ebde Use the syscall insn for system calls. Fix up some assembly to 
remove either previously made errors, or to account for the
fact that syscall clobbers %ecx.

92d8b1e9fa Revert previous: .S files are currently compiled with -traditional-cpp, 
so __STDC__ is _not_ always defined.

6bd902a1db Adapt for recent lib/libc/softfloat changes. 2002-05-22 10:20:20 +00:00

936b7f4cf8 Import the 32-bit version of SoftFloat 2a and separate it and the 64-bit 
version into different directories.  Which version a given port uses is
controlled by the SOFTFLOAT_BITS make variable.  This is set to 64 (which
uses the same code we had before) by default.  32-bit platforms that don't
need extended precision support might get better performance by using 32.

Set the ARM port to use the 32-bit version of SoftFloat, since this is more
than a factor of two faster than the 64-bit version.  This should get the
floating-point performance back to what it was in 1.5.

010758bf16 Add SIGFPE support to SoftFloat, so fpsetmask/fpgetmask now work. A new 
variable, float_exception_mask (#defined to _softfloat_float_exception_mask)
contains the current exception mask.
Also make the argument to float_raise into an fp_except.
Also synchronise file header comments between files.

33ce495df4 Put R6 back in the save and adjust frame size for it. Don't save the 
register in sigset area, put them after the sigset area.

583d4ad39f Put R6 back in save mask (to make mask used by PLT routines). Adjust frame 
size according.  In _longjmp, deal with sp/fp separately since they stored
in reserve order so movq won't work.

a1fe3592c6 Correct mistaken signature for _Qp_dtoq. It gets a double passed in, not 
a pointer to double which causes obvious errors on evaluation

12810ed37d Use size_t in prototype (so this will be LP64 clean for PPC64 someday). 
Calculate len separately for icache & dcache in case each has different
cacheline widths.  Make the code for both loops the same except for the
dcbst/icbi.  Deal with sizes >=2GB properly (like that'll happen but ...)

2d8577fb83 Clean up some rampant code duplication wrt ieee number handling: 
- Add alignment-safe double and float unions.
 - Use the above for the __infinity and __nan constants on all
   architectures that use the standard ieee754 representation of
   those constants.
 - Add a single copy of various ieee754 math functions (frexp, isinf,
   isnan, ldexp and modf) that had numerous duplicates among the
   arch-specific directories.
 - Use the above functions on all architectures where the generic C
   versions where used.  Architectures that had local assembly
   routines are untouched (for those functions only).
