AMDGPU: Fix promote alloca pass creating huge arrays This was assuming it could use all memory before, which is a bad decision because it restricts occupancy. By default, only try to use enough space that could reduce occupancy to 7, an arbitrarily chosen limit. Based on the exist LDS usage, try to round up to the limit in the current tier instead of further hurting occupancy. This isn't ideal, because it doesn't accurately know how much space is going to be used for alignment padding. llvm-svn: 269708

[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

AMDGPU: Fix promote alloca pass creating huge arrays This was assuming it could use all memory before, which is a bad decision because it restricts occupancy. By default, only try to use enough space that could reduce occupancy to 7, an arbitrarily chosen limit. Based on the exist LDS usage, try to round up to the limit in the current tier instead of further hurting occupancy. This isn't ideal, because it doesn't accurately know how much space is going to be used for alignment padding. llvm-svn: 269708
