092f718fed There is some very odd code in s_exp2.c that only works if 'double' 
values are rounded to 53 bit mantissa in teh x87 registers.
This hasn't been true since Nov 11 2013.
Forcing a store-load for 'double' in STRICT_ASSIGN() seems to fix things
  (at least enough for the few random test cases).
I suspect the code could be changed so that the number of mantissa bits
  didn't matter.

54d90457f6 If dlopen returns NULL assume we are statically linked and return, 
rather than getting a warning when dlinfo fails.

300f37afc0 Do not process linkmaps if there is exactly one link map present 
(i.e. there is no ld.so).  Makes statically linked rump kernels work on
glibc (at least for me).

based on some discussion with Justin Cormack

7a17404a6d XXX This is all wrong and needs new tables and constants - but at least use 
constants in the VAX double range for now, so it is compilable with newer
gcc.

cf83766ecf Revert conversion to __thread as breaks on archs without TLS support 2014-03-10 22:37:51 +00:00
justin
587ef2949a Use __thread rather than pthread_getspecific for rumpuser curlwp. 
This has better performance and curlwp is a performance bottleneck
in rump kernel code.

1b5cff8f1d Move to a flat space register convention. %sr[4-7] are all now the space 
number allocated to the process.  gcc produces (slightly) better code
with this convention.

Retain backwards compatiblity.

c479ba2f5a Avoid a warning and just do the trap #1 instead of calling sigreturn inline. 
If it fails, it'll fall into the botch case so don't bother calling CERROR
on failure.

77e93a9cb9 Drop in a fabs() after the fsqrt(). 
While it may seem pointless, it the rouding mode is set to round towards
minus infinity then acos(-1) calculates atan2(sqrt(1.0 - 1.0), -1) the subtract
generates -0.0 which sqrt() preserves.
atan2(-0, -1) is -pi, but acos(-1) is expected to be +pi.
This might 'fix' the test failures seen in some environments, but they
are not failing due to an obvously incorrent x87 rounding mode.

afa90f2bf5 prepare for moving GCC 4.5 into gcc.old: 
- convert to using ${EXTERNAL_GCC_SUBDIR}
- define base-external-gpl3-gcc* subdir as GCC_SUBDIR
- use <bsd.init.mk> over <bsd.own.mk> for a bunch of places; mostly
  because it arranges for ../Makefile.inc to be included earlier, and
  don't bother including the latter if the former is already included.
- move all .PATH: settings after <bsd.{own,lib}.mk> so that all
  valid variables are set before it is evaluated
- rename mknative-gcc* to match their subdir name.

XXX the relationship between the Makefile.inc/Makefile.gcc_path files
    is kind of sketchy, it would be great if this was fixed.
