fix PR6197 - infinite recursion in ipsccp due to block addresses

2010-02-01T19:35:08Z

evaluateICmpRelation wasn't handling blockaddress. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94993 91177308-0d34-0410-b5e6-96231b3b80d8

Fix a crasher trying to fold each element in a comparison between two vectors

2010-01-21T07:03:21Z

if one of the vectors didn't have elements (such as undef). Fixes PR 6096. Fix an issue in the constant folder where fcmp (<2 x %ty>, <2 x %ty>) would have <2 x i1> type if constant folding was successful and i1 type if it wasn't. This exposed a related issue in the bitcode reader. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94069 91177308-0d34-0410-b5e6-96231b3b80d8

fix PR5978 by peeling the loop so that we avoid shifting the

result int by 8 for the first byte. While normally harmless, if the result is smaller than a byte, this shift is invalid. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93018 91177308-0d34-0410-b5e6-96231b3b80d8

fix PR5287, a serious regression from my previous patches. Thanks to

implements something out of Target/README.txt producing: _foo: ## @foo movl 4(%esp), %eax movapd LCPI1_0, %xmm0 movapd %xmm0, (%eax) ret $4 instead of: _foo: ## @foo movl 4(%esp), %eax movapd _b, %xmm0 mulpd LCPI1_0, %xmm0 addpd _a, %xmm0 movapd %xmm0, (%eax) ret $4 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84942 91177308-0d34-0410-b5e6-96231b3b80d8

teach libanalysis to fold int and fp loads from almost arbitrary

2009-10-23T06:23:49Z

non-type-safe constant initializers. This sort of thing happens quite a bit for 4-byte loads out of string constants, unions, bitfields, and an interesting endianness check from sqlite, which is something like this: const int sqlite3one = 1; # define SQLITE_BIGENDIAN (*(char *)(&sqlite3one)==0) # define SQLITE_LITTLEENDIAN (*(char *)(&sqlite3one)==1) # define SQLITE_UTF16NATIVE (SQLITE_BIGENDIAN?SQLITE_UTF16BE:SQLITE_UTF16LE) all of these macros now constant fold away. This implements PR3152 and is based on a patch started by Eli, but heavily modified and extended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84936 91177308-0d34-0410-b5e6-96231b3b80d8

Teach vm core to more aggressively fold 'trunc' constantexprs,

2009-10-17T21:53:27Z

allowing it to simplify the crazy constantexprs in the testcases down to something sensible. This allows -std-compile-opts to completely "devirtualize" the pointers to member functions in the testcase from PR5176. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84368 91177308-0d34-0410-b5e6-96231b3b80d8
