R600: Correctly handle vertex fetch clauses the precede ENDIFs The control flow finalizer would sometimes use an ALU_POP_AFTER instruction before the vetex fetch clause instead of using a POP instruction after it. llvm-svn: 199917

; RUN: llc -march=r600 -mcpu=redwood %s -o - | FileCheck %s
; This tests for a bug where vertex fetch clauses right before an ENDIF
; instruction where being emitted after the ENDIF. We were using ALU_POP_AFTER
; for the ALU clause before the vetex fetch instead of emitting a POP instruction
; after the fetch clause.

[opaque pointer type] Add textual IR support for explicit type parameter to load instruction Essentially the same as the GEP change in r230786. A similar migration script can be used to update test cases, though a few more test case improvements/changes were required this time around: (r229269-r229278) import fileinput import sys import re pat = re.compile(r"((?:=|:|^)\s*load (?:atomic )?(?:volatile )?(.*?))(| addrspace\(\d+\) *)\*($| *(?:%|@|null|undef|blockaddress|getelementptr|addrspacecast|bitcast|inttoptr|\[\[[a-zA-Z]|\{\{).*$)") for line in sys.stdin: sys.stdout.write(re.sub(pat, r"\1, \2\3*\4", line)) Reviewers: rafael, dexonsmith, grosser Differential Revision: http://reviews.llvm.org/D7649 llvm-svn: 230794
