2013-04-29Rewrite some tests with FileCHeck in X86 codegenMichael Liao
- Revise previous patches of the same purpose by fixing *) grep <PA> | not grep <PB> semantically is not the same as CHECK: <PA>{{^<PB>.*$}} as the former will check all occurrences of <PA> while the later only check the first match. As the result, CHECK needs putting in all place where <PA> occurs. *) grep <PA> | count <N> needs a final CHECK-NOT of the same pattern. (As 'CHECK-<N>' is proposed for discussion, converting 'grep | count <N>' where N > 1 is postponed.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180742 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-29Add getSymbolAlignment to the ObjectFile interface.Rafael Espindola
For regular object files this is only meaningful for common symbols. An object file format with direct support for atoms should be able to provide alignment information for all symbols. This replaces getCommonSymbolAlignment and fixes test-common-symbols-alignment.ll on darwin. This also includes a fix to MachOObjectFile::getSymbolFlags. It was marking undefined symbols as common (already tested by existing mcjit tests now that it is used). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180736 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-29SimplifyCFG: If convert single conditional storesArnold Schwaighofer
This resurrects r179957, but adds code that makes sure we don't touch atomic/volatile stores: This transformation will transform a conditional store with a preceeding uncondtional store to the same location: a[i] = may-alias with a[i] load if (cond) a[i] = Y into an unconditional store. a[i] = X may-alias with a[i] load tmp = cond ? Y : X; a[i] = tmp We assume that on average the cost of a mispredicted branch is going to be higher than the cost of a second store to the same location, and that the secondary benefits of creating a bigger basic block for other optimizations to work on outway the potential case where the branch would be correctly predicted and the cost of the executing the second store would be noticably reflected in performance. hmmer's execution time improves by 30% on an imac12,2 on ref data sets. With this change we are on par with gcc's performance (gcc also performs this transformation). There was a 1.2 % performance improvement on a ARM swift chip. Other tests in the test-suite+external seem to be mostly uninfluenced in my experiments: This optimization was triggered on 41 tests such that the executable was different before/after the patch. Only 1 out of the 40 tests (dealII) was reproducable below 100% (by about .4%). Given that hmmer benefits so much I believe this to be a fair trade off. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180731 91177308-0d34-0410-b5e6-96231b3b80d8

Solves the problem of a module with no triple on the command line and no triple in the module using non-gdb ok features on darwin. Fix up the member-pointers test to check the correct things for cross platform (DW_FORM_flag is a good prefix). Unfortunately no testcase because I have no ideas how to test something without a triple and without a triple in the module yet check precisely on two platforms.

2013-04-25Mips assembler: .set reorder supportJack Carter
Mips have delayslots for certain instructions like jumps and branches. These are instructions that follow the branch or jump and are executed before the jump or branch is completed. Early Mips compilers could not cope with delayslots and left them up to the assembler. The assembler would fill the delayslots with the appropriate instruction, usually just a nop to allow correct runtime behavior. The default behavior for this is set with .set reorder. To tell the assembler that you don't want it to mess with the delayslot one used .set noreorder. For backwards compatibility we need to support .set reorder and have it be the default behavior in the assembler. Our support for it is to insert a NOP directly after an instruction with a delayslot when in .set reorder mode.

2013-04-25Remove SMLoc paired with CHECK-NOT patterns. Not functionality change.Michael Liao
Pattern has source location by itself. After adding a trivial method to retrieve it, it's unnecessary to pair a source location for CHECK-NOT patterns. One thing revised after this is the diagnostic info is more accurate by pointing to the start of the CHECK-NOT pattern instead of the end of the CHECK-NOT pattern. E.g. diagnostic message previously looks like <stdin>:1:1: error: CHECK-NOT: string occurred! test ^ test.txt:1:16: note: CHECK-NOT: pattern specified here CHECK-NOT: test ^ is changed to <stdin>:1:1: error: CHECK-NOT: string occurred! test ^ test.txt:1:12: note: CHECK-NOT: pattern specified here CHECK-NOT: test ^ git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180578 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-24LoopVectorize: Scalarize padded typesArnold Schwaighofer
This patch disables memory-instruction vectorization for types that need padding bytes, e.g., x86_fp80 has 10 bytes store size with 6 bytes padding in darwin on x86_64. Because the load/store vectorization is performed by the bit casting to a packed vector, which has incompatible memory layout due to the lack of padding bytes, the present vectorizer produces inconsistent result for memory instructions of those types. This patch checks an equality of the AllocSize of a scalar type and allocated size for each vector element, to ensure that there is no padding bytes and the array can be read/written using vector operations.
