Bill Wendling 633c48ec1d r98363 deleted a '!' when cleaning up whitespace. This caused globals which are 
*not* declarations to *not* be placed in the "preserve" list.

Sean Callanan 62232d90cf Fixed EDOperand to use the operand type, not the 
flags, to determine whether or not the operand is
a memory operand.

Chris Lattner 4422d31b84 introduce a new CallGraphSCC class, and pass it around 
to CallGraphSCCPass's instead of passing around a
std::vector<CallGraphNode*>.  No functionality change,
but now we have a much tidier interface.

Dan Gohman ff9ecb2824 Make the export files absolute paths, and change Makefile.rules 
to expect them this way, to fix srcdir!=objdir builds.

Dan Gohman 473a53f7b1 Generalize the EXPORTED_SYMBOL_FILE concept in the Makefiles to work with 
native linking export files, including running sed to prepend underscores
on darwin, and make use of it in libLTO and libEnhancedDisassembly.

Remove the leading underscores from library export files so that they
work with the new EXPORTED_SYMBOL_FILE support.

Douglas Gregor 9078f954bf Unbreak CMake build by improving the EnhancedDisassembly makefile a 
bit (we're not trying to build a shared library yet) and generating
the X86GenEDInfo.inc and ARMGenEDInfo.inc files as necessary.

llvm-svn: 101188
 2010-04-13 22:47:43 +00:00
Sean Callanan 814e69b171 Fixed a nasty layering violation in the edis source 
code.  It used to #include the enhanced disassembly
information for the targets it supported straight
out of lib/Target/{X86,ARM,...} but now it uses a
new interface provided by MCDisassembler, and (so
far) implemented by X86 and ARM.

Also removed hacky #define-controlled initialization
of targets in edis.  If clients only want edis to
initialize a limited set of targets, they can set
--enable-targets on the configure command line.

llvm-svn: 101179
 2010-04-13 21:21:57 +00:00
Ted Kremenek 8af6f765f5 Add CMake support for 'edis'.

Chris Lattner 6b2b064d7a Make the disassembler respect the assembler dialect when printing instructions, 
patch by Marius Wachtler!

llvm-svn: 101160
 2010-04-13 18:41:17 +00:00
Sean Callanan d75c8a0813 Build system fix to make llvm-mc properly build 
after edis.  Really, there ought to be some
mechanism to ensure that PARALLEL_DIRS get built
after DIRS.

llvm-svn: 101095
 2010-04-12 23:55:28 +00:00
Sean Callanan 393c4df342 Build system fixes. llvm-mc depends on 
libEnhancedDisassembly, so we now build the
static library in all cases (although the shared
library is only built when requested/possible).

Also, fixed a bug where edis wasn't properly
initializing the targets it uses.

llvm-svn: 101072
 2010-04-12 21:55:49 +00:00
Sean Callanan deee643b95 Bug fix: made the enhanced disassembler's link 
flags work properly when EDIS_VERSION is defined

llvm-svn: 101063
 2010-04-12 20:23:08 +00:00
Sean Callanan 2d03d3a8a7 Second try at integrating the edis tester. This 
time I use the LIBS variable, which is not subject
to a %.a -> -l% transformation, to link llvm-mc
against libEnhancedDisassembly.

llvm-mc -edis works the same as llvm-mc
-disassemble, but outputs tokens and operands.

 2010-04-10 23:18:13 +00:00
Sean Callanan a4ae4e7693 Updated the edis build mechanism to allow for builds 
that do not build some (or all) of the targets that
edis supports.

llvm-svn: 100910
 2010-04-10 00:48:10 +00:00
Chris Lattner 55ddc30f07 revert r100842 which broke several of the build bots. 
llvm-svn: 100848
 2010-04-09 04:24:20 +00:00
Sean Callanan 844a7febd3 Added a tester for the enhanced disassembler, 
integrated into the llvm-mc testing tool.

llvm-svn: 100842
 2010-04-09 01:43:16 +00:00
Sean Callanan 48b1804e79 Bugfixes for edis. Code to initialize instruction 
state was being executed too lazily, and the LLVM
assembly syntax for the disassembler was not being
written into the proper disassembler state variable.

llvm-svn: 100830
 2010-04-09 00:11:15 +00:00
Sean Callanan 03549ee5af Added support for ARM disassembly to edis. 
I also added a rule to the ARM target's Makefile to
build the ARM-specific instruction information table
for the enhanced disassembler.

I will add the test harness for all this stuff in
a separate commit.

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
$ 

don't stop at inc!

Chris Lattner 7012916275 fix an ugly wart in the MCInstPrinter api where the 
raw_ostream to print an instruction to had to be specified
at MCInstPrinter construction time instead of being able
to pick at each call to printInstruction.

 2010-04-03 21:03:50 +00:00
Chris Lattner 07d09ed49a Add special case bitcode support for DebugLoc. This avoids 
having the bitcode writer materialize mdnodes for all the
debug location tuples when writing out the bc file and 
stores the information in a more compact form.  For example,
the -O0 -g bc file for combine.c in 176.gcc shrinks from
739392 to 512096 bytes.

This concludes my planned short-term debug info work.

Sean Callanan dfc8a75755 Updated the install location for EnhancedDisassembly
