 2006-12-07 22:21:48 +00:00
Chris Lattner 700b873130 Detemplatize the Statistic class. The only type it is instantiated with 
is 'unsigned'.

Jim Laskey 311622f912 ExternalWeak case in wrong location. 
llvm-svn: 32073
 2006-12-01 14:37:39 +00:00
Evan Cheng 5fb2c76d59 A initialized global variable cannot be extern weak. However, if a global value's initializer is itself a external weak symbol, emit the weak reference.

Chris Lattner 8c6a41ea12 start using PPC predicates more consistently. 
llvm-svn: 31833
 2006-11-17 22:10:59 +00:00
Chris Lattner 30055b9208 fix a regression that I introduced. stdu should scale the offset by 4 
before printing it.

 2006-11-16 21:45:30 +00:00
Chris Lattner 6be726048e Go through all kinds of trouble to mark 'blr' as having a predicate operand 
that takes a register and condition code.  Print these pieces of BLR the
right way, even though it is currently set to 'always'.

Next up: get the JIT encoding right, then enhance branch folding to produce
predicated blr for simple examples.

Reid Spencer de46e48420 For PR786: 
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

Anton Korobeynikov aa4c0f9374 1. Clean up code due to changes in SwitchTo*Section(2) 
2. Added partial debug support for mingw\cygwin targets (the same as
   Linux\ELF). Please note, that currently mingw\cygwin uses 'stabs' format
   for storing debug info by default, thus many (runtime) libraries has
   this information included. These formats shouldn't be mixed in one binary
   ('stabs' & 'DWARF'), otherwise binutils tools will be confused.

Chris Lattner 41e22a5419 emit jump table before debug info 
llvm-svn: 30731
 2006-10-05 00:26:05 +00:00
Chris Lattner aad26a19f0 Always emit the jump table after the function so it's part of the same 'atom' 
as the function body.

 2006-10-05 00:24:46 +00:00
Chris Lattner a81a75c390 The DarwinAsmPrinter need not check for isDarwin. createPPCAsmPrinterPass 
should create the right asmprinter subclass.

llvm-svn: 30542
 2006-09-20 17:12:19 +00:00
Chris Lattner 8597a2fc4e Wrap some darwin'isms with isDarwin checks.

Evan Cheng d7572fb234 Encode pc-relative conditional branch offset as pc+(num of bytes / 4). The 
asm printer will print it as offset*4. e.g. bne cr0, $+8.

The PPC code emitter was expecting the offset to be number of instructions, not
number of bytes. This fixes a whole bunch of JIT failures.

llvm-svn: 29885
 2006-08-25 21:54:44 +00:00
Nate Begeman 984c1a4a8f Emit .set directives for jump table entries when possible, which reduces 
the number of relocations in object files, shrinkifying them.

complete.

ppc64 mode!

llvm-svn: 28923
 2006-06-27 01:02:25 +00:00
Jim Laskey a7b2bd5997 Add and sort "sections" in debug lines. This always stepping through 
code in sections other than ".text", including weak sections like ctors and
dtors.

llvm-svn: 28909
 2006-06-23 12:51:53 +00:00
Chris Lattner 52a956da52 Rename OR4 -> OR. Move some PPC64-specific stuff to the 64-bit file 
llvm-svn: 28889
