Devang Patel 3ebd8931fb One instruction may start (or end) multiple lexical scopes.
There is no need to remember labels identifying regions marked by such instructions in each scope.

Chris Lattner 1e45789ee0 introduce a new recoverable error handling API to LLVMContext
and use it in one place in inline asm handling stuff.  Before
we'd generate this for an invalid modifier letter:

$ clang asm.c -c -o t.o
fatal error: error in backend: Invalid operand found in inline asm: 'abc incl    ${0:Z}'
INLINEASM <es:abc incl    ${0:Z}>, 10, %EAX<def>, 2147483657, %EAX, 14, %EFLAGS<earlyclobber,def,dead>, <!-1>


Now we generate this:

$ clang asm.c -c -o t.o
error: invalid operand in inline asm: 'incl    ${0:Z}'
asm.c:3:12: note: generated from here
  __asm__ ("incl    %Z0" : "+r" (X));
           ^
1 error generated.

This is much better but still admittedly not great ("why" is the operand 
invalid??), codegen should try harder with its diagnostics :)

John McCall 796583eec0 Fix a number of clang -Wsign-compare warnings that didn't have an obvious
solution.  The only reason these don't fire with gcc-4.2 is that gcc turns off
part of -Wsign-compare in C++ on accident.

Stuart Hastings 4bd3dd956f Reverting 100530 & 100531 due to regressions in the GDB test suite.
llvm-svn: 100563
2010-04-06 21:38:29 +00:00
Stuart Hastings c067196984 Revise debug info machinery to digest nested functions and classes.
A certain GDB testsuite case (local.cc) has a function nested inside a
class nested inside another function.  GCC presents the innermost
function to llvm-convert first.  Heretofore, the debug info mistakenly
placed the inner function at module scope.  This patch walks the GCC
context links and instantiates the outer class and function so the
debug info is properly nested.  Radar 7426545.

Chris Lattner 3b21e4d404 Give AsmParser an option to control whether it finalizes
the stream.  New demo:

$ clang asm.c -S -o - -emit-llvm | llc -filetype=obj -o t.o
$ otool -tv t.o
t.o:
(__TEXT,__text) section
_foo:
0000000000000000	subq	$0x08,%rsp
0000000000000004	movl	%edi,(%rsp)
0000000000000007	movl	%edi,%eax
0000000000000009	incl	%eax
000000000000000b	movl	%eax,(%rsp)
000000000000000e	movl	%eax,0x04(%rsp)
0000000000000012	addq	$0x08,%rsp

Chris Lattner 8900ef1931 add .o file writing for inline asm in llc. Here's a silly
demo:

$ clang asm.c -S -o - -emit-llvm | llc -filetype=obj -o t.o
<inline asm>:1:2: error: unrecognized instruction
	abc incl    %eax
	^
LLVM ERROR: Error parsing inline asm

Only problem seems to be that the parser finalizes OutStreamer 
at the end of the first inline asm, which isn't what we want.
For example:

$ cat asm.c
int foo(int X) {
 __asm__ ("incl    %0" : "+r" (X));
 return X;
}
$ clang asm.c -S -o - -emit-llvm | llc
...
	subq	$8, %rsp
	movl	%edi, (%rsp)
	movl	%edi, %eax
	## InlineAsm Start
	incl    %eax
	## InlineAsm End
	movl	%eax, (%rsp)
	movl	%eax, 4(%rsp)
	addq	$8, %rsp
	ret
$ clang asm.c -S -o - -emit-llvm | llc -filetype=obj -o t.o
$ otool -tv t.o
t.o:
(__TEXT,__text) section
_foo:
0000000000000000	subq	$0x08,%rsp
0000000000000004	movl	%edi,(%rsp)
0000000000000007	movl	%edi,%eax
0000000000000009	incl	%eax

Chris Lattner 28f2fdafcd hopefully sate the clang self host build, which is apparently
instantiating some folding set stuff that GCC isn't, requiring 
some types to not be incomplete.

I don't know if clang is right or wrong, but unbreaking the
bot is goodness.  Here's the broken build:
