* Rewrite some tests with FileCHeck in X86 codegenMichael Liao2013-04-2920-28/+85
| | | | | | | | | | | | | | | - 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

* Emit the TLS initialization function pointers into the correct section.Bill Wendling2013-04-292-0/+16
| | | | | | | | | | | The `llvm.tls_init_funcs' (created by the front-end) holds pointers to the TLS initialization functions. These need to be placed into the correct section so that they are run before `main()'. <rdar://problem/13733006> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180737 91177308-0d34-0410-b5e6-96231b3b80d8
* Add getSymbolAlignment to the ObjectFile interface.Rafael Espindola2013-04-2910-21/+51
| | | | | | | | | | | | | 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

* SimplifyCFG: If convert single conditional storesArnold Schwaighofer2013-04-292-4/+198
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* Handle tied sub-operands in AsmMatcherEmitterUlrich Weigand2013-04-271-30/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem this patch addresses is the handling of register tie constraints in AsmMatcherEmitter, where one operand is tied to a sub-operand of another operand. The typical scenario for this to happen is the tie between the "write-back" register of a pre-inc instruction, and the base register sub-operand of the memory address operand of that instruction. The current AsmMatcherEmitter code attempts to handle tied operands by emitting the operand as usual first, and emitting a CVT_Tied node when handling the second (tied) operand. However, this really only works correctly if the tied operand does not have sub-operands (and isn't a sub-operand itself). Under those circumstances, a wrong MC operand list is generated. In discussions with Jim Grosbach, it turned out that the MC operand list really ought not to contain tied operands in the first place; instead, it ought to consist of exactly those operands that are named in the AsmString. However, getting there requires significant rework of (some) targets. This patch fixes the immediate problem, and at the same time makes one (small) step in the direction of the long-term solution, by implementing two changes: 1. Restricts the AsmMatcherEmitter handling of tied operands to apply solely to simple operands (not complex operands or sub-operand of such). This means that at least we don't get silently corrupt MC operand lists as output. However, if we do have tied sub-operands, they would now no longer be handled at all, except for: 2. If we have an operand that does not occur in the AsmString, and also isn't handled as tied operand, simply emit a dummy MC operand (constant 0). This works as long as target code never attempts to access MC operands that do no not occur in the AsmString (and are not tied simple operands), which happens to be the case for all targets where this situation can occur (ARM and PowerPC). [ Note that this change means that many of the ARM custom converters are now superfluous, since the implement the same "hack" now performed already by common code. ] Longer term, we ought to fix targets to never access *any* MC operand that does not occur in the AsmString (including tied simple operands), and then finally completely remove all such operands from the MC operand list. Patch approved by Jim Grosbach. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180677 91177308-0d34-0410-b5e6-96231b3b80d8

* Add target flags to MachineMemOperands.Andrew Trick2013-04-271-1/+7
| | | | | | | | | | | | | | | | | | This seems to me an obvious place to allow target passes to annotate memory operations. There are plenty of bits, and I'm not aware of another good way for early target passes to propagate hints along to later passes. Target independent transforms can simply preserve them, the way they preserve the other flags. Like MachineMemOperands in general, if the target flags are lost we must still generate correct code. This has lots of uses, but I want this flexibility now to make it easier to work with the new MachineTraceMetrics analysis. MachineTraceMetrics can gather a lot of information about instructions based on the surrounding code. This information can be used to influence postRA machine passes that don't work on SSA form. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180666 91177308-0d34-0410-b5e6-96231b3b80d8

* Use llvm/Object/MachO.h in macho-dumper. Drop the old macho parser.Rafael Espindola2013-04-269-976/+347
| | | | | | | | | | | | | | | | | | | | | For Mach-O there were 2 implementations for parsing object files. A standalone llvm/Object/MachOObject.h and llvm/Object/MachO.h which implements the generic interface in llvm/Object/ObjectFile.h. This patch adds the missing features to MachO.h, moves macho-dump to use MachO.h and removes ObjectFile.h. In addition to making sure that check-all is clean, I checked that the new version produces exactly the same output in all Mach-O files in a llvm+clang build directory (including executables and shared libraries). To test the performance, I ran macho-dump over all the files in a llvm+clang build directory again, but this time redirecting the output to /dev/null.
