Chris Lattner a5ca93cdd5 make SectionFlagsForGlobal a private static function instead of a public 
virtual one.

Chris Lattner b34d0a2fcb There is no need to pass the name into lib/Target/TargetAsmInfo.cpp 
when we have a global with no section explicitly specified.

Chris Lattner 0f5ebf5509 Replace UniqueSectionForGlobal with getSectionPrefixForUniqueGlobal. 
The later doesn't depend on any crazy LLVM IR stuff, and this
pulls the concatenation of prefix with GV name (the root problem behind
PR4584) out one level.

Chris Lattner 308c7896a4 "fix" PR4612, which is a crash on: 
%0 = malloc [3758096384 x i32]

The "malloc" instruction doesn't support 64-bits correctly (see PR715),
and should be removed.  Victor is actively working on fixing this, in 
the meantime just don't crash.

Duncan Sands f4981105ca Revert r75581: it causes massive breakage in the Ada 
testsuite, due to exception handling not working
correctly.  Maybe because the libgcc unwinder is
miscompiled - not sure, and I won't have time to
look into it before leaving on holiday.  Note that
miscompilations of libgcc are not picked up by the
nightly testers, because they dynamically link with
libgcc, so pick up the system version rather than
the version built as part of llvm-gcc.  This is a
nasty flaw in the nightly testers.  (On the other
hand the Ada testsuite links with the just built
libgcc).

Evan Cheng 95a73e2eab Since we have moved unified assembly, switch to ADR instruction instead of a the difficult-to-read .set + add syntax to materialize pc-relative address. 
Turns out this also fixed a poor code selection on Thumb1. I have no idea why we were using a mov + add to do the same thing as ADR before.

   the old style.

__m128i b(__m128 a, __m128 b) { return a!=a | b!=b; }

to:

_a:
	cmpordps	%xmm1, %xmm0
	ret
_b:
	cmpunordps	%xmm1, %xmm0
	ret

with clang instead of to a ton of horrible code.

well since it has a different ABI (a convenient way to test both the 
reg and mem forms of these instructions).

Reid Kleckner 1a722d9b73 Make the JIT code emitter properly retry and ask for more memory when it runs 
out of memory, and also make the default memory manager allocate more memory
when it runs out.

Also, switch function stubs and global data over to using the BumpPtrAllocator.

This makes it so the JIT no longer mmaps (or the equivalent on Windows) 16 MB
of memory, and instead allocates in 512K slabs.  I suspect this size could go
lower, especially on embedded platforms, now that more slabs can be allocated.

llvm-svn: 76828
 2009-07-23 00:49:59 +00:00
Reid Kleckner 5bd6105d65 Parameterize the BumpPtrAllocator over a slab allocator. It defaults to using 
malloc, so there should be no functional changes to other code.

These changes are necessary since I have plans to use this allocator in the JIT
memory manager, and it needs a special allocator.

I also added some tests which helped me pinpoint some bugs.
