* Re-commit r86077 now that r86290 fixes the 179.art and 175.vpr ARM regressions.Victor Hernandez2009-11-071-1/+3
| | | | | | | | | | | | | | | | | | | | | | | Here is the original commit message: This commit updates malloc optimizations to operate on malloc calls that have constant int size arguments. Update CreateMalloc so that its callers specify the size to allocate: MallocInst-autoupgrade users use non-TargetData-computed allocation sizes. Optimization uses use TargetData to compute the allocation size. Now that malloc calls can have constant sizes, update isArrayMallocHelper() to use TargetData to determine the size of the malloced type and the size of malloced arrays. Extend getMallocType() to support malloc calls that have non-bitcast uses. Update OptimizeGlobalAddressOfMalloc() to optimize malloc calls that have non-bitcast uses. The bitcast use of a malloc call has to be treated specially here because the uses of the bitcast need to be replaced and the bitcast needs to be erased (just like the malloc call) for OptimizeGlobalAddressOfMalloc() to work correctly. Update PerformHeapAllocSRoA() to optimize malloc calls that have non-bitcast uses. The bitcast use of the malloc is not handled specially here because ReplaceUsesOfMallocWithGlobal replaces through the bitcast use. Update OptimizeOnceStoredGlobal() to not care about the malloc calls' bitcast use. Update all globalopt malloc tests to not rely on autoupgraded-MallocInsts, but instead use explicit malloc calls with correct allocation sizes. llvm-svn: 86311

* Revert 85678/85680. The decision is to stay with the current form of Chris Lattner2009-11-013-10/+6
| | | | | | | indirectbr, thus we don't need "blockaddr(@func, null)". Eliminate it for simplicity. llvm-svn: 85699
* Make blockaddress(@func, null) be valid, and make 'deleting a basic Chris Lattner2009-10-313-6/+10
| | | | | | | | | | | | block with a blockaddress still referring to it' replace the invalid blockaddress with a new blockaddress(@func, null) instead of a inttoptr(1). This changes the bitcode encoding format, and still needs codegen support (this should produce a non-zero value, referring to the entry block of the function would also be quite reasonable). llvm-svn: 85678
* add bitcode reader support for blockaddress. We can now fullyChris Lattner2009-10-282-2/+45
| | | | | | | | | | round trip blockaddress through .ll and .bc files, so add a testcase. There are still a bunch of places in the optimizer and other places that need to be updated to work with these constructs, but at least the basics are in now. llvm-svn: 85377

* Previously, all operands to Constant were themselves constant.Chris Lattner2009-10-281-3/+4
| | | | | | | | | In the new world order, BlockAddress can have a BasicBlock operand. This doesn't permute much, because if you have a ConstantExpr (or anything more specific than Constant) we still know the operand has to be a Constant. llvm-svn: 85375

* Make changes to rev 84292 as requested by Chris Lattner.Victor Hernandez2009-10-211-7/+4
| | | | | | | Most changes are cleanup, but there is 1 correctness fix: I fixed InstCombine so that the icmp is removed only if the malloc call is removed (which requires explicit removal because the Worklist won't DCE any calls since they can have side-effects). llvm-svn: 84772

| | | | | | | | Update testcases that rely on malloc insts being present. Also prematurely remove MallocInst handling from IndMemRemoval and RaiseAllocations to help pass tests in this incremental step. llvm-svn: 84292

| | | | | | | | | | | | | | | | | Constant uniquing tables. This allows distinct ConstantExpr objects with the same operation and different flags. Even though a ConstantExpr "a + b" is either always overflowing or never overflowing (due to being a ConstantExpr), it's still necessary to be able to represent it both with and without overflow flags at the same time within the IR, because the safety of the flag may depend on the context of the use. If the constant really does overflow, it wouldn't ever be safe to use with the flag set, however the use may be in code that is never actually executed. This also makes it possible to merge all the flags tests into a single test. llvm-svn: 80998

* Make LLVM command-line tools overwrite their output files without -f.Dan Gohman2009-08-251-1/+1
| | | | | | | | | | | | | | | | This is conventional command-line tool behavior. -f now just means "enable binary output on terminals". Add a -f option to llvm-extract and llvm-link, for consistency. Remove F_Force from raw_fd_ostream and enable overwriting and truncating by default. Introduce an F_Excl flag to permit users to enable a failure when the file already exists. This flag is currently unused. Update Makefiles and documentation accordingly. llvm-svn: 79990
