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

2005-03-15This mega patch converts us from using Function::a{iterator|begin|end} toChris Lattner
using Function::arg_{iterator|begin|end}. Likewise Module::g* -> Module::global_*. This patch is contributed by Gabor Greif, thanks! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20597 91177308-0d34-0410-b5e6-96231b3b80d8

2005-02-13Make the check for global variables the same as the one for functions. InReid Spencer
both cases they are looking for non-external variables/functions that do not have internal linkage. Using "!isExternal()" is a little more understandable than "hasInitializer()" git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20155 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
2005-02-13Do not put internal symbols into the symbol table. This shrinks the symbolChris Lattner
table for archives in common cases, and prevents trying to resolve a external reference with an internal reference. This shrinks the libpython.a symbol table from 126302 to 19770 bytes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20151 91177308-0d34-0410-b5e6-96231b3b80d8
2005-01-31Fix the regressions my User changes introduced. Apparently some parts ofChris Lattner
LLVM make the very reasonable assumption that constant expressions will have at least one operand! :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19943 91177308-0d34-0410-b5e6-96231b3b80d8

2004-12-21For PR351:Reid Spencer
Remove unix specific code (use of errno and read) from the reader. Thanks to Jeff Cohen for pointing this out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19081 91177308-0d34-0410-b5e6-96231b3b80d8

2004-12-13For PR351:Reid Spencer
Use sys::MappedFile instead of ReadFileIntoAddressSpace and UnmapFileFromAddressSpace. sys::MappedFile has the nice property that it cleans up after itself so exception handling can be removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18902 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

2004-12-04Do not allow bytecode files with unresolved references to be read. DoingChris Lattner
