Fangrui Song	dbc96b518b	Revert "[CodeGenModule] Assume dso_local for -fpic -fno-semantic-interposition" This reverts commit `789a46f2d7`. Accidentally committed.	2020-02-03 10:09:39 -08:00
Fangrui Song	789a46f2d7	[CodeGenModule] Assume dso_local for -fpic -fno-semantic-interposition Summary: Clang -fpic defaults to -fno-semantic-interposition (GCC -fpic defaults to -fsemantic-interposition). Users need to specify -fsemantic-interposition to get semantic interposition behavior. Semantic interposition is currently a best-effort feature. There may still be some cases where it is not handled well.

Craig Topper	5dd94e50c9	[CodeGen] Update test checks missed in r345168. These tests don't run unless the aarch64 target is registered and my testing had been on an x86 only build directory. llvm-svn: 345176	2018-10-24 18:45:44 +00:00
Mehdi Amini	6aa9e9b41a	IRGen: Add optnone attribute on function during O0 Amongst other, this will help LTO to correctly handle/honor files compiled with O0, helping debugging failures. It also seems in line with how we handle other options, like how -fnoinline adds the appropriate attribute as well.

Tim Northover	58672974a9	ARM & AArch64: convert asm tests to LLVM IR and restrict optimizations. This is mostly a one-time autoconversion of tests that checked assembly after "-Owhatever" compiles to only run "opt -mem2reg" and check the assembly. This should make them much more stable to changes in LLVM so they won't break on unrelated changes. "opt -mem2reg" is a compromise designed to increase the readability of tests that check dataflow, while minimizing dependency on LLVM. Hopefully mem2reg is stable enough that no surpises will come along. Should address http://llvm.org/PR26815. llvm-svn: 263048	2016-03-09 18:54:42 +00:00
Tim Northover	831d728f9a	AArch64: re-enable tests that were looking for a non-existent backend. In the final phase of the merge, I managed to disable a bunch of Clang tests accidentally. Fortunately none of them seem to have broken in the interim. llvm-svn: 211149	2014-06-18 08:37:28 +00:00
Tim Northover	25e8a6754e	AArch64/ARM64: update Clang after AArch64 removal. A few (mostly CodeGen) parts of Clang were tightly coupled to the AArch64 backend. Now that it's gone, they will not even compile. I've also deduplicated RUN lines in many of the AArch64 tests. This might improve "make check-all" time noticably: some of those NEON tests were monsters. llvm-svn: 209578	2014-05-24 12:51:25 +00:00
James Molloy	75f5f9e629	[ARM64] Allow the disabling of NEON and crypto instructions. Update tests to pass -target-feature +neon. llvm-svn: 206394	2014-04-16 15:33:48 +00:00
Tim Northover	a2ee433c8d	ARM64: initial clang support commit. This adds Clang support for the ARM64 backend. There are definitely still some rough edges, so please bring up any issues you see with this patch. As with the LLVM commit though, we think it'll be more useful for merging with AArch64 from within the tree. llvm-svn: 205100	2014-03-29 15:09:45 +00:00
Tim Northover	926a235fea	AArch64: convert NEON tests to use CHECK-LABEL. llvm-svn: 202703	2014-03-03 11:34:36 +00:00
Jiangning Liu	37f5bb1b28	Implement AArch64 Neon instruction set Bitwise Extract. llvm-svn: 194119	2013-11-06 02:26:12 +00:00
