* Allow compatible extension attributes for tail callsTim Northover2013-08-121-3/+3
| | | | | | | | If the tail-callee and caller give the same bits via the same signext/zeroext attribute then a tail-call should be allowed, since the extension has already been done by the callee. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188159 91177308-0d34-0410-b5e6-96231b3b80d8

* X86: use sub-register sequences for MOV*r0 operationsTim Northover2013-05-301-2/+2
| | | | | | | | | | | | Instead of having a bunch of separate MOV8r0, MOV16r0, ... pseudo-instructions, it's better to use a single MOV32r0 (which will expand to "xorl %reg, %reg") and obtain other sizes with EXTRACT_SUBREG and SUBREG_TO_REG. The encoding is smaller and partial register updates can sometimes be avoided. Until recently, this sequence was a barrier to rematerialization though. That should now be fixed so it's an appropriate time to make the change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182928 91177308-0d34-0410-b5e6-96231b3b80d8

The patch also includes changes to sibcall.ll and movgs.ll, which were failing on the Atom buildbot after the first patch was applied. This patch by Sriram Murali. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178193 91177308-0d34-0410-b5e6-96231b3b80d8
* Flip the new block-placement pass to be on by default.Chandler Carruth2012-04-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This is mostly to test the waters. I'd like to get results from FNT build bots and other bots running on non-x86 platforms. This feature has been pretty heavily tested over the last few months by me, and it fixes several of the execution time regressions caused by the inlining work by preventing inlining decisions from radically impacting block layout. I've seen very large improvements in yacr2 and ackermann benchmarks, along with the expected noise across all of the benchmark suite whenever code layout changes. I've analyzed all of the regressions and fixed them, or found them to be impossible to fix. See my email to llvmdev for more details. I'd like for this to be in 3.1 as it complements the inliner changes, but if any failures are showing up or anyone has concerns, it is just a flag flip and so can be easily turned off. I'm switching it on tonight to try and get at least one run through various folks' performance suites in case SPEC or something else has serious issues with it. I'll watch bots and revert if anything shows up. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154816 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix an inconsistency in the x86 backend that led it to reject "calll foo" onChris Lattner2010-09-221-12/+12
| | | | | | | | | | | | | x86-32: 32-bit calls were named "call" not "calll". 64-bit calls were correctly named "callq", so this only impacted x86-32. This fixes rdar://8456370 - llvm-mc rejects 'calll' This also exposes that mingw/64 is generating a 32-bit call instead of a 64-bit call, I will file a bugzilla. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114534 91177308-0d34-0410-b5e6-96231b3b80d8
