2009-09-26builtin_trap should be noreturn, this fixes PR5062, patch byChris Lattner
Roman Divacky! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82876 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-23implement support for __builtin_eh_return_data_regno on x86-32 and x86-64.Chris Lattner
This implements PR5034 and rdar://6836445. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82614 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-08Fix the atomics sema code to convert operands to the argument typesChris Lattner
of the underlying _N builtin, not the the type of the pointee of the actual type. This ensures that atomics involving pointers end up using the correct integer type when they are resolved, avoiding aborts in codegen. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71218 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-08reimplement __sync_* builtins to be variadic and to follow the sameChris Lattner
semantic rules that gcc and icc use. This implements the variadic and concrete versions as builtins and has sema do the disambiguation. There are probably a bunch of details to finish up but this seems like a large monotonic step forward :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71212 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-28Simplify the scheme used for keywords, and change the classification Eli Friedman
scheme to be more useful. The new scheme introduces a set of categories that should be more readable, and also reflects what we want to consider as an extension more accurately. Specifically, it makes the "what is a keyword" determination accurately reflect whether the keyword is a GNU or Microsoft extension. I also introduced separate flags for keyword aliases; this is useful because the classification of the aliases is mostly unrelated to the classification of the original keyword. This patch treats anything that's in the implementation namespace (prefixed with "__", or "_X" where "X" is any upper-case letter) as a keyword without marking it as an extension. This is consistent with the standards in that an implementation is allowed to define arbitrary extensions in the implementation namespace without violating the standard. This gets rid of all the nasty "extension used" warnings for stuff like __attribute__ in -pedantic mode. We still warn for extensions outside of the the implementation namespace, like typeof. If someone wants to implement -Wextensions or something like that, we could add additional information to the keyword table. This also removes processing for the unused "Boolean" language option; such an extension isn't supported on any other C implementation, so I don't see any point to adding it. The changes to test/CodeGen/inline.c are required because previously, we weren't actually disabling the "inline" keyword in -std=c89 mode. I'll remove Boolean and NoExtensions from LangOptions in a follow-up commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70281 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-05Fix rdar://5905347 a crash on invalid builtin, due to theChris Lattner
params not getting installed for builtins when synthesized. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50676 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-04add comments for the various AssignConvertType's, and split int->pointer ↵Chris Lattner
from pointer->int. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45591 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-04Merge all the 'assignment' diagnostic code into one routine, decloning Chris Lattner
it from several places. This merges the diagnostics, making them more uniform and fewer in number. This also simplifies and cleans up the code. Some highlights: 1. This removes a bunch of very-similar diagnostics. 2. This renames AssignmentCheckResult -> AssignConvertType 3. This merges PointerFromInt + IntFromPointer which were always treated the same. 4. This updates a bunch of test cases that have minor changes to the produced diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45589 91177308-0d34-0410-b5e6-96231b3b80d8
