4a7a113a30 * x86: Fixed attributes of the LEAVE instruction - it reads EBP. 
This fixes crashes with -O3s in some cases due to an incorrect peephole
  optimization.

b8befe3d1f * Fixed a typo in the condition, though it seems this code path is not used now. 2021-09-15 12:25:48 +03:00

a7e234254f * x86: Do not replace inc/dec with add/sub 1 because this code path is 
executed only for the C_Z,C_NZ,C_E,C_NE conditions, so inc/dec can be
  used.

940ac567a5 * Patch by J. Gareth "Kit" Moreton (issue #39343). Added missing allocation 
of flags in tx86typeconvnode.second_int_to_bool and in generic
  tcgtypeconvnode.second_int_to_bool. This fixes random failures of the
  tcnvint1 test and some other tests when compiled with -O2.
