* target-alpha: Fix float32_to_s vs zero exponent.Richard Henderson2009-12-171-12/+32
| | | | | | | | | There was a bug in float32_to_s that incorrectly mapped a zero exponent to 0x38. This meant 0.0f != 0. At the same time, fix a generic type punning bug in helper_memory_to_s and helper_s_to_memory. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

* target-alpha: Implement fp branch/cmov inline.Richard Henderson2009-12-171-31/+0
| | | | | | | | | | | The old fcmov implementation had a typo: - tcg_gen_mov_i64(cpu_fir[rc], cpu_fir[ra]); which moved the condition, not the second source, to the destination. But it's also easy to implement the simplified fp comparison inline. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

* target-alpha: Fixes for alpha-linux syscalls.Richard Henderson2009-12-131-39/+2
| | | | | | | | | | | | | | | | | | 1. Add correct definitions of error numbers. 2. Implement SYS_osf_sigprocmask 3. Implement SYS_osf_get/setsysinfo for IEEE_FP_CONTROL. This last requires exposing the FPCR value to do_syscall. Since this value is actually split up into the float_status, expose routines from helper.c to access it. Finally, also add a float_exception_mask field to float_status. We don't actually use it to control delivery of exceptions to the emulator yet, but simply hold the value that we placed there when loading/storing the FPCR.

* Revert "Get rid of _t suffix"Anthony Liguori2009-10-011-1/+1
| | | | | | | | | | | | In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

* target-alpha: fix cmpbge instructionaurel322008-11-101-1/+1
| | | | | | | | | | | | The cmpbge instruction should compare all 8 bytes of one 64-bit value with another. However, we were looping with a < 7 condition which was skipping the top byte. So if we were doing a compare where the top byte was important, we could get the wrong result (this notably breaks the strlen() function with certain sized strings).
