Previosy, if actual instruction have one of optional operands then other optional operands listed before this also should be presented. For example instruction v_fract_f32 v0, v1, mul:2 have one optional operand - OMod and do not have optional operand clamp. Previously this was not allowed because clamp is listed before omod in AsmString: string AsmString = "v_fract_f32$vdst, $src0_modifiers$clamp$omod"; Making this work required some hacks (both OMod and Clamp match classes have same PredicateMethod). Now, if MatchInstructionImpl meets formal optional operand that is not presented in actual instruction it skips this formal operand and tries to match current actual operand with next formal. Patch by: Sam Kolton Review: http://reviews.llvm.org/D17568 [AMDGPU] Assembler: Check immediate types for several optional operands in predicate methods With this change you should place optional operands in order specified by asm string: clamp -> omod offset -> glc -> slc -> tfe Fixes for several tests. Depends on D17568 Patch by: Sam Kolton Review: http://reviews.llvm.org/D17644 llvm-svn: 262314 |
