2005-10-23When a function takes a variable number of pointer arguments, with a zeroJeff Cohen
pointer marking the end of the list, the zero *must* be cast to the pointer type. An un-cast zero is a 32-bit int, and at least on x86_64, gcc will not extend the zero to 64 bits, thus allowing the upper 32 bits to be random junk. The new END_WITH_NULL macro may be used to annotate a such a function so that GCC (version 4 or newer) will detect the use of un-casted zero at compile time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23888 91177308-0d34-0410-b5e6-96231b3b80d8
2005-10-03Use a map to cache the ModuleType information, so we can do logarithmicChris Lattner
lookups instead of linear time lookups. This speeds up bc parsing of a large file from 137.834u 118.256s 4:27.96 to 132.611u 114.436s 4:08.53 with a release build. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23611 91177308-0d34-0410-b5e6-96231b3b80d8

2005-02-13Make sure to clear the LazyFunctionLoadMap after we ParseAllFunctionBodies.Chris Lattner
Otherwise, clients who call ParseAllFunctionBodies will attempt to parse the function bodies twice, which is (uh) very very bad (tm). This fixes gccld on python. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20152 91177308-0d34-0410-b5e6-96231b3b80d8

2004-12-09Eliminate this ugly hack. This was put back in when replaceAllUsesOf usedChris Lattner
a different algorithm that was extremely inefficient for instructions with many operands. This reduces the time of this code snippet from .23s for 176.gcc to 0.03s in a debug build, which speeds up total llvm-dis time just barely. It's more of a code cleanup than a speedup. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18685 91177308-0d34-0410-b5e6-96231b3b80d8

2004-09-27The system ranlib on darwin occasionally adds two extra newlines to theChris Lattner

2004-08-21Bytecode Reader Cleanup:Reid Spencer
- provide the correct conversion for ModuleBlockID in read_block (a potential bug but not actually exploited because reading module block ids doesn't use read_block). - install support for handleTypeList handler - install support for handleDependentLibrary handler - install support for handleTargetTriple handler - clean up comments, output strings, - ensure that processing function arguments doesn't SIGSEGV if one of the arguments is a null pointer (yeah, it happened .. weird) - prepare for version 5 bytecode by documenting what will change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15981 91177308-0d34-0410-b5e6-96231b3b80d8
