On sh3 __udivsi3 is gcc "millicode" with special calling convention
...
(less registers clobbered than usual). Each DSO that needs it gets
its own hidden copy from libgcc.a. Do not compile udivsi3.c for sh3
here since this C version doesn't conform to what gcc expects and
overrides the libgcc.a version.
This makes binaries compiled with gcc4.8 work. The issue was not
exposed with gcc4.5 since it uses different division strategy by
default.

Simplify somewhat: this is C not FORTRAN-IV - we have structures!
...
Directly us 'ieee_double_shape_type' when ripping apart the fp number
to avoid an extra store-load in 'STRICT_ASSIGN'.
Keep 'k' as the exponent, only do 'k << 20' when generating the fp number
from it.
Fix infinity and underflow returns on i386 - because the value is returned
in %st0 (x87 stack) we have to generate a long double error value.
The returned value for integers -1023 and below (which should be denormal
fp valuesr) are 'just plain wrong' (tm).
2014-03-16 22:44:48 +00:00

Fix overflow and underflow on i386.
...
The return value of a 'float' function is in the x87 %st(0) register.
This is an 80bit 'long double' register.
If you multiply 0x1p100f by 0x1p100f the caller sees 0x1p200 - not the
expected infinity.
So use a 'double' value which goes through a store-load sequence to generate
the required exception and value.

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.

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.
