These are two related changes (one in llvm, one in clang). LLVM: - rename address_safety => sanitize_address (the enum value is the same, so we preserve binary compatibility with old bitcode) - rename thread_safety => sanitize_thread - rename no_uninitialized_checks -> sanitize_memory CLANG: - add __attribute__((no_sanitize_address)) as a synonym for __attribute__((no_address_safety_analysis)) - add __attribute__((no_sanitize_thread)) - add __attribute__((no_sanitize_memory)) for S in address thread memory If -fsanitize=S is present and __attribute__((no_sanitize_S)) is not set llvm attribute sanitize_S llvm-svn: 176075

polygen grammar for LLVM assembly language.
|
|
|
|
This file defines an LLVM assembly language grammar for polygen,
|
|
which is a tool for generating random text based on a grammar.
|
|
It is strictly syntax-based, and makes no attempt to generate
|
|
IR that is semantically valid. Most of the IR produced doesn't
|
|
pass the Verifier.

Define rules for non-keyword tokens. This is currently just a bunch
|
|
of hacks. They don't cover many valid forms of tokens, and they also
|
|
generate some invalid forms of tokens. The LLVM parser has custom
|
|
C++ code to lex these; custom C++ code for emitting them would be
|
|
convenient, but polygen doesn't support that.
