Sometimes users do not specify data layout in LLVM assembly and let llc set the data layout by target triple after loading the LLVM assembly. Currently the parser checks alloca address space no matter whether the LLVM assembly contains data layout definition, which causes false alarm since the default data layout does not contain the correct alloca address space. The parser also calls verifier to check debug info and updating invalid debug info. Currently there is no way to let the verifier to check debug info only. If the verifier finds non-debug-info issues the parser will fail. For llc, the fix is to remove the check of alloca addr space in the parser and disable updating debug info, and defer the updating of debug info and verification to be after setting data layout of the IR by target. For other llvm tools, since they do not override data layout by target but instead can override data layout by a command line option, an argument for overriding data layout is added to the parser. In cases where data layout overriding is necessary for the parser, the data layout can be provided by command line. Differential Revision: https://reviews.llvm.org/D41832 llvm-svn: 323826
