* target-sparc: Use cpu_loop_exit_restore from helper_check_ieee_exceptionsRichard Henderson2016-07-121-4/+13
| | | | | | | This avoids needing to save state before every FP operation. Tested-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Signed-off-by: Richard Henderson <rth@twiddle.net>
* target-sparc: Use explicit writes to cpu_fsrRichard Henderson2016-07-121-150/+73Star
| | | | | | | | | | By arranging for explicit writes to cpu_fsr after floating point operations, we are able to mark the helpers as not writing to tcg globals, which means that we don't need to invalidate the integer register set across said calls.

* sparc: Clean up includesPeter Maydell2016-01-291-0/+1
| | | | | | | | | | Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes.

* tcg: Invert the inclusion of helper.hRichard Henderson2014-05-281-1/+1
| | | | | | | | | | Rather than include helper.h with N values of GEN_HELPER, include a secondary file that sets up the macros to include helper.h. This minimizes the files that must be rebuilt when changing the macros for file N. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <rth@twiddle.net>
* target-sparc: fix fcmp{s,d,q} instructions wrt exceptionAurelien Jarno2012-09-081-40/+27Star
| | | | | | | | | | | | | | | | | | | | | | 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
