Chris Lattner a9d0b5800a Fix SingleSource/Regression/C/2004-08-12-InlinerAndAllocas.c on Sparc. 
The ABI specifies that there is a register save area at the bottom of the
stack, which means the actual used pointer needs to be an offset from
the subtracted value.

Duraid Madina cbbc184a2e HP aCC (and a bunch of other compilers, no doubt) don't share 
GCC's syntax for auto-dependency generation stuff. This should
be changed to be disabling dependency stuff unless GCC/ICC is
found.

Duraid Madina 09518d0c73 previously, configure would die if GCC or ICC was not found. Now it'll 
go through, but we do want to know if we're using GCC/ICC since they
share certain funky command line options (for dependency generation
stuff)

Chris Lattner 684f911241 new testcase that broke unswitch due to loopsimplify not doing the right thing.

 2006-02-14 23:07:29 +00:00
Chris Lattner 9c5693fb2a Canonicalize inner loops before outer loops. Inner loop canonicalization 
can provide work for the outer loop to canonicalize.

This fixes a case that breaks unswitching.

Evan Cheng 0451499b3c Doh again!

Chris Lattner cffbbee8d1 When splitting exit edges to canonicalize loops, make sure to put the new 
block in the appropriate loop nest.

Third time is the charm, right?

Chris Lattner e3c793a71a new note 
llvm-svn: 26186
 2006-02-14 22:19:54 +00:00
Chris Lattner b134520b86 If we have zero initialized data with external linkage, use .zerofill to 
emit it (instead of .space), saving a bit of space in the .o file.

For example:
int foo[100];
int bar[100] = {};

when compiled with C++ or -fno-common results in shrinkage from 1160 to 360
bytes of space.  The X86 backend can also do this on darwin.

XMM registers were not being handled.

Evan Cheng 6a37456d73 Set maxStoresPerMemSet to 16. Ditto for maxStoresPerMemCpy and 
maxStoresPerMemMove. Although the last one is not used.

target specific theshold, e.g. 16 for x86.

Chris Lattner ecd162d5cd Adjust to new form of handling lexer dependencies, this way shouldn't have 
the problems the old way did.

llvm-svn: 26161
 2006-02-14 05:13:13 +00:00
Chris Lattner 8104b4c352 Implement an alternative way of handling generated lex files in CVS. This 
should solve the "updating cvs when .l files change give me conflict markers
that break my build" issue.

 2006-02-14 01:01:41 +00:00
Chris Lattner 8e2ee7358f Fix a latent bug in the call sequence handling stuff. Some targets (e.g. x86) 
create these nodes with flag results.  Remember that we legalized them.

Chris Lattner 7d8522884b If any of the sign extended bits are demanded, the input sign bit is demanded 
for a sign extension.

This fixes InstCombine/2006-02-13-DemandedMiscompile.ll and Ptrdist/bc.

llvm-svn: 26152
