| | | | | | | | | | | | | | | | | | | According to PR2536, the old spiller had trouble with the IMPLICIT_DEF in this code: %reg1028<def> = MOV16rm %reg0, 1, %reg0, <ga:g_5>, Mem:LD(2,2) [g_5 + 0] %reg1039<def> = IMPLICIT_DEF %reg1038<def> = INSERT_SUBREG %reg1039, %reg1028, 2 %reg1025<def> = AND32ri %reg1038, 65534, %%EFLAGS<imp-def> However, today we emit a zero-extending load instead: %vreg10<def> = MOVZX32rm16 %noreg, 1, %noreg, <ga:@g_5>, %noreg; %mem:LD2[@g_5] GR32:%vreg10 %vreg0<def> = AND32ri %vreg10, 65534, %%EFLAGS<imp-def,dead>; %GR32:%vreg0,%vreg10 This makes the test pointless since it no longer creates the spiller hazard. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132210 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix the inliner to maintain the current de facto invoke semantics:John McCall2011-05-271-0/+103
| | | | | | | | | | | | | | | | - the selector for the landing pad must provide all available information about the handlers, filters, and cleanups within that landing pad - calls to _Unwind_Resume must be converted to branches to the enclosing lpad so as to avoid re-entering the unwinder when the lpad claimed it was going to handle the exception in some way This is quite specific to libUnwind-based unwinding. In an effort to not interfere too badly with other unwinders, and with existing hacks in frontends, this only triggers on _Unwind_Resume (not _Unwind_Resume_or_Rethrow) and does nothing with selectors if it cannot find a selector call for either lpad. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132200 91177308-0d34-0410-b5e6-96231b3b80d8

* Assorted fixes for Win64 EH unwind info emission:Charles Davis2011-05-271-4/+13
| | | | | | | | | | | - Flip order of bitfields. This gets our output matching GAS. - Handle case where the end of the prolog wasn't specified. - If the resulting unwind info struct is less than 8 bytes, pad to 8 bytes.
