| | | | | | | | | | | | | | | integer and floating-point opcodes, introducing FAdd, FSub, and FMul. For now, the AsmParser, BitcodeReader, and IRBuilder all preserve backwards compatability, and the Core LLVM APIs preserve backwards compatibility for IR producers. Most front-ends won't need to change immediately. This implements the first step of the plan outlined here: http://nondot.org/sabre/LLVMNotes/IntegerOverflow.txt llvm-svn: 72897

* Update the list of function annotations for nocapture. All of these came upNick Lewycky2009-02-151-47/+186
| | | | | | | | | | | when I was looking at functions used by python. Highlights include, better largefile support (64-bit file sizes on 32-bit systems), fputs string is nocapture, popen/pclose added (popen being noalias return), modf and frexp and friends. Also added some missing 'break' statements and combined identical sections. llvm-svn: 64615
* Mark strto* as readonly when the endptr is null.Nick Lewycky2009-02-131-1/+3

| | | | | | | | | | | | | | | | | | | putc, puts, perror, vscanf and vsscanf from getting annotations. Add annotations for eight printf functions, memalign, pread and pwrite. On Linux, llvm-gcc sometimes renames strdup, getc, putc, strtok_r, scanf and sscanf. Match the alternate function names. Fix a crash annotating opendir. Don't mark fsetpos's second parameter as nocapture. It's supposed to be captured. Do mark fopen's path and mode strings as nocapture. Mark ferror as readonly, but not fileno which may set errno. llvm-svn: 62456
* Move the libcall annotating part from doFinalization to doInitialization.Nick Lewycky2009-01-051-18/+77
| | | | | | | | | | | | | Finalization occurs after all the FunctionPasses in the group have run, which is clearly not what we want. This also means that we have to make sure that we apply the right param attributes when creating a new function. Also, add a missed optimization: strdup and strndup. NoCapture and NoAlias return! llvm-svn: 61658
* Run a post-pass that marks known function declarations by name.Nick Lewycky2009-01-041-0/+443
