John McCall cfcb775b56 Add an option to disable the LLVM verifier pass (which is still always 
disabled in NDEBUG builds).  The option applies only to -cc1 invocations and is:
  -disable_llvm_verifier

flaw.

Sean Callanan dde9c12307 Reworked the Intel disassembler to support instructions 
whose opcodes extend into the ModR/M field using the
Form field of the instruction rather than by special
casing each instruction.  Commented out the special
casing of VMCALL, which is the first instruction to use
this special form.  While I was in the neighborhood,
added a few comments for people modifying the Intel
disassembler.

Dale Johannesen 626b79d6a6 Add the problem I just hacked around in 96015/96020. 
The solution there produces correct code, but is seriously
deficient in several ways.

Chris Lattner 4ad96055fb implement infrastructure to support fixups for rip-rel 
addressing.  This isn't complete because I need an MCContext
to generate new MCExprs.

Ted Kremenek a3e657064b Make the following functions thread-safe but having them return an std::string that is reconstructed 
every time they are called:

Fariborz Jahanian 5ec502e35b Complain if block-literal expression's parameter name is 
missing (in c/objc mode). Fixes radar 7528255.

Dale Johannesen 26062150fa When save/restoring CR at prolog/epilog, in a large 
stack frame, the prolog/epilog code was using the same
register for the copy of CR and the address of the save slot.  Oops.
This is fixed here for Darwin, sort of, by reserving R2 for this case.
A better way would be to do the store before the decrement of SP,
which is safe on Darwin due to the red zone.

SVR4 probably has the same problem, but I don't know how to fix it;
there is no red zone and R2 is already used for something else.
I'm going to leave it to someone interested in that target.

Better still would be to rewrite the CR-saving code completely;
spilling each CR subregister individually is horrible code.

 2010-02-12 19:35:25 +00:00
Chris Lattner 5647d3192c fix a bug in SourceManager::getInstantiationLocSlowCase, where 
we'd add an offset from the spelling location space to the 
instantiation location, which doesn't make sense and would
lead up to the text diagnostics crashing when presented with
non-sensical locations.

This fixes rdar://7597492, a crash on 255.vortex.

llvm-svn: 96004

Fariborz Jahanian dc68f9539c Patch to fix a warning which exposed a bug in building 
a qualified objective-c pointer type. Fixes radar 7638810.

Chris Lattner fc38aa7091 restructure code a bit: there are two potential issues 
worth asserting about in this code: 1) if the source range
is bogus (begin loc after end loc), and 2) if the client
is trying to highlight a range that is purely whitespace.

It is possible to just silently ignore #2, but it seems like
it is always a bug, so lets keep asserting on this condition,
but with a better assert message.

Dale Johannesen 30d99f4b9b Rewrite handling of DBG_VALUE; previous algorithm 
didn't handle
X =
Y<dead> = use X
DBG_VALUE(X)
I was hoping to avoid this approach as it's slower,
but I don't think it can be done.

Chris Lattner 75879be9d8 1. modernize the constantmerge pass, using densemap/smallvector. 
2. don't bother trying to merge globals in non-default sections,
   doing so is quite dubious at best anyway.
3. fix a bug reported by Arnaud de Grandmaison where we'd try to
   merge two globals in different address spaces.
