as much, etc.

Daniel Dunbar 1f982105a6 Add StringRef::{substr, startswith}. 
llvm-svn: 76559
 2009-07-21 09:18:49 +00:00
Evan Cheng 07a6ac6b29 Another rewriter bug exposed by recent coalescer changes. ReuseInfo::GetRegForReload() should make sure the "switched" register is in the desired register class. I'm surprised this hasn't caused more failures in the past.

Evan Cheng a7bb55ebb6 Fix a dagga combiner bug: avoid creating illegal constant. 
Is this really a winning transformation?
fold (shl (srl x, c1), c2) -> (shl (and x, (shl -1, c1)), (sub c2, c1)) or

llvm-svn: 76505

Dan Gohman 00c1aaec5a Remove the code that tried to evaluate whether (A pred B) is known 
by determining if (B pred (B-A)) is known, as it doesn't handle
overflow correctly.

llvm-svn: 76504
 2009-07-20 23:53:35 +00:00
Dale Johannesen a2d2adfa4e Make sure a global matching asm 'i' constraint gets its 
flags set properly.  (hasMemory is clearly irrelevant
when matching 'i', I don't understand what this was
supposed to be doing.)
gcc.apple/asm-block-25.c (test passed before by

Bill Wendling dde1a8eef4 Pass in the unfortunately named "LessPrivatePrefix" for the 
"LinkerPrivatePrefix". It seems to have been used in only one place before I
started this "linker_private" business. I'm thinking that a rename is in
order...

 2009-07-20 20:32:43 +00:00
Kevin Enderby ee5513582d Removed the DumpSymbolsandMacros and LoadSymbolsandMacros MCStreamer API as 
the parsing of the .dump and .load should be done in the assembly parser and
not have any need for an MCStreamer API.  Changed the code for now so these
just produce an error saying these specific directives are not yet implemented
since they are likely no longer used and may never need to be implemented.

 2009-07-20 17:44:17 +00:00
Dan Gohman 33a3fd0b9c Revert the addition of hasNoPointerOverflow to GEPOperator. 
Getelementptrs that are defined to wrap are virtually useless to
optimization, and getelementptrs that are undefined on any kind
of overflow are too restrictive -- it's difficult to ensure that
all intermediate addresses are within bounds. I'm going to take
a different approach.

Remove a few optimizations that depended on this flag.

Bill Wendling a3c6f6bffa Add plumbing for the `linker_private' linkage type. This type is meant for 
"private" symbols which the assember shouldn't strip, but which the linker may
remove after evaluation. This is mostly useful for Objective-C metadata.

This is plumbing, so we don't have a use of it yet. More to come, etc.

Eli Friedman 916a0f3262 Switch Alpha over to the new call lowering style. New code mostly 
copied from the SystemZ target.  I don't think this causes any 
significant changes to the output (I compared the assembly, and the 
results appeared to be essentially unchanged), although I don't actually 
have an Alpha to test on.

I would appreciate if anyone with the appropriate hardware could test 
this. I'm not sure if that includes anyone subscribed to llvm-commits, 
though.
