Ted Kremenek 8bafa2cf9f Internally store the body of a BlockExpr using a Stmt* instead of a CompoundStmt*, and use the getBody() method to do the appropriate checking. This both removes the type-punning warnings in Expr.cpp and also makes BlockExpr have more consistency checks against modifications to its body (via StmtIterator).

Devang Patel 597e70876e Now Attributes are divided in three groups 
- return attributes - inreg, zext and sext
- parameter attributes
- function attributes - nounwind, readonly, readnone, noreturn

Return attributes use 0 as the index.
Function attributes use ~0U as the index.

Devang Patel a05633e105 Now Attributes are divided in three groups 
- return attributes - inreg, zext and sext
- parameter attributes
- function attributes - nounwind, readonly, readnone, noreturn

Return attributes use 0 as the index.
Function attributes use ~0U as the index.

This patch requires corresponding changes in llvm-gcc and clang.

Chris Lattner c88a23e8d7 Fix the rest of rdar://6243860 hopefully. This requires changing FileIDInfo 
to whether the fileid is a 'extern c system header' in addition to whether it
is a system header, most of this is spreading plumbing around.  Once we have that,
PPLexerChange bases its "file enter/exit" notifications to PPCallbacks to
base the system header state on FileIDInfo instead of HeaderSearch.  Finally,
in Preprocessor::HandleIncludeDirective, mirror logic in GCC: the system headerness
of a file being entered can be set due to the #includer or the #includee.

its size).  Adjust various lowering functions to
pass this info through from CallInst.  Use it to

Dan Gohman 007a6bb9b9 Factor out the code for determining when symblic addresses 
require RIP-relative addressing and use it to fix a bug
in X86FastISel in x86-64 PIC mode, where it was trying to
use base/index registers with RIP-relative addresses. This
fixes a bunch of x86-64 testsuite failures.

llvm-svn: 56670
 2008-09-26 18:07:51 +00:00
Chris Lattner e744d32b72 emulate a bit of GCC path lookup weirdness: if a system 
directory is shadowed by a user directory in the lookup
path, ignore the user directory not the system one.  Not
doing this can affect file lookup and the "is a system
header" bit on locations.  For example:
  clang -v -I/usr/include inc.c -E | & grep /usr/inc
now prints:

# 1 "/usr/include/i386/_types.h" 1 3 4
# 37 "/usr/include/i386/_types.h" 3 4
# 70 "/usr/include/i386/_types.h" 3 4

instead of:

# 1 "/usr/include/i386/_types.h" 1
# 37 "/usr/include/i386/_types.h"
# 70 "/usr/include/i386/_types.h"

This is part of rdar://6243860.
