Chris Lattner 51065568cd Have the inst emitter add the !srcloc mdnode to the machine instr. 
Have the asmprinter use the mdnode to scavenge a source location if
present.  Document this nonsense in langref.

Dan Gohman 6232f73c7b PerformTailCallOpt was renamed to GuaranteedTailCallOpt to 
better reflect its meaning, now that tail call optimizations
are done by default in some cases.

David Greene 9641d06809 Add support for emitting non-temporal stores for DAGs marked 
non-temporal.  Fix from r96241 for botched encoding of MOVNTDQ.

Add documentation for !nontemporal metadata.

Add a simpler movnt testcase.

Charles Davis be5557e86b Add a new function attribute, 'alignstack'. It will indicate (when the backends 
implement support for it) that the stack should be forcibly realigned in the
prologue (and the process reversed in the epilogue).

Jakob Stoklund Olesen 74bb06c0f0 Reintroduce the InlineHint function attribute. 
This time it's for real! I am going to hook this up in the frontends as well.

The inliner has some experimental heuristics for dealing with the inline hint.
When given a -respect-inlinehint option, functions marked with the inline
keyword are given a threshold just above the default for -O3.

We need some experiments to determine if that is the right thing to do.

users.

Jeffrey Yasskin b867746a05 Clarify the requirements for a "tail call" to actually be optimized into a 
jump.  People clearly weren't finding the extra requirements in
CodeGenerator.html.

Eric Christopher 31e39bd3d4 Update docs for bitcode changes. For object size checking we won't 
work with partial objects so just count the type as a boolean. Update
appropriately.

Dan Gohman c74bc28297 The inbounds keyword isn't relevant to overindexing of 
static array types. Thanks to Duncan for pointing this out!

llvm-svn: 86576
 2009-11-09 19:01:53 +00:00
Dan Gohman 66c4d61010 Remove the "special case" for zero-length arrays, and rephrase this 
paragraph to be more precise.

llvm-svn: 86572
 2009-11-09 18:40:39 +00:00
Chris Lattner a381effe72 add the ability for TargetData to return information about legal integer 
datatypes on a given CPU.  This is intended to allow instcombine and other
transformations to avoid converting big sequences of operations to an
inconvenient width, and will help clean up after SRoA.  See also "Adding 
legal integer sizes to TargetData" on Feb 1, 2009 on llvmdev, and PR3451.

Comments welcome.

Chris Lattner aa99c94e2a Revert 85678/85680. The decision is to stay with the current form of 
indirectbr, thus we don't need "blockaddr(@func, null)".  Eliminate it
for simplicity.

llvm-svn: 85699
 2009-11-01 01:27:45 +00:00
Chris Lattner b2c0e243c5 Make blockaddress(@func, null) be valid, and make 'deleting a basic 
block with a blockaddress still referring to it' replace the invalid 
blockaddress with a new blockaddress(@func, null) instead of a 
inttoptr(1).

This changes the bitcode encoding format, and still needs codegen 
support (this should produce a non-zero value, referring to the entry
block of the function would also be quite reasonable).

Gabor Greif 03ab4dcff9 use metavariable <result> instead of SSA name %result for consistency
