* target-sparc: fix fcmp{s,d,q} instructions wrt exceptionAurelien Jarno2012-09-081-40/+27
| | | | | | | | | | | | | | | | | | | | | | fcmp{s,d,q} instructions are supposed to ignore quiet NaN (contrary to the fcmpe{s,d,q} instructions), but the current code is wrongly setting the NV exception in that case. Moreover the current code is duplicated: first the arguments are checked for NaN to generate an exception, and later in case the comparison is unordered (which can only happens if one of the argument is a NaN), the same check is done to generate an exception. Fix that by calling clear_float_exceptions() followed by check_ieee_exceptions() as for the other floating point instructions. Use the _compare_quiet functions for fcmp{s,d,q} and the _compare ones for fcmpe{s,d,q}. Simplify the flag setting by not clearing a flag that is set the line just below. This fix allows the math glibc testsuite to pass. Cc: Blue Swirl <blauwirbel@gmail.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

* target-sparc: Do exceptions management fully inside the helpers.Richard Henderson2011-10-261-60/+146
| | | | | | | | This reduces the size of the individual translation blocks, since we only emit a single call for each FOP rather than three. In addition, clear_float_exceptions expands inline to a single byte store. Signed-off-by: Richard Henderson <rth@twiddle.net>
* target-sparc: Make FPU/VIS helpers const when possible.Richard Henderson2011-10-261-1/+1
| | | | | | This also removes the unused ENV parameter from these helpers. Signed-off-by: Richard Henderson <rth@twiddle.net>

* Sparc: avoid AREG0 for float and VIS opsBlue Swirl2011-10-231-35/+35
| | | | | | | | Make floating point and VIS ops take a parameter for CPUState instead of relying on global env. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
* Sparc: split FPU and VIS op helpersBlue Swirl2011-10-231-0/+394
Move FPU op helpers to fop_helper.c. Move VIS op helpers to vis_helper.c, compile it only for Sparc64. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
