Chris Lattner 9df647539d Refactor the priority mechanism one step further: now that it is a separate 
class, sever its implementation from the interface.  Now we can provide new
implementations of the same interface (priority computation) without touching
the scheduler itself.

Chris Lattner c683a7232b Make the new and old front-ends more similar: now neither uses __main.

Chris Lattner e363fdf318 Add support for 'special' llvm globals like debug info and static ctors/dtors.

 2006-03-09 01:39:46 +00:00
Chris Lattner fdb533a1f6 Fix a really annoying bug in bugpoint that made reducing C++ testcases 
almost impossible with the new CFE.  It now guarantees that the static
ctor/dtor list is correctly split between the modules.

Chris Lattner d0eb1d12d2 Fit to 80 columns. 
Add support for running static ctor/dtors that aren't handled by __main.
This fixes programs with the JIT and the new CFE, such as HBD.

Jim Laskey 2370265550 libstdc++-v3 was failing to build. Needed to handle composite types with empty 
members (running into a zero initializer.)

 2006-03-08 02:07:02 +00:00
Chris Lattner fc34f8bb48 Fix a miscompilation of 188.ammp with the new CFE. 188.ammp is accessing 
arrays out of range in a horrible way, but we shouldn't break it anyway.
Details in the comments.

Evan Cheng 70b25efa57 X86ISD::REP_STOS and X86ISD::REP_MOVS now produces a flag. 
llvm-svn: 26604
 2006-03-07 23:34:23 +00:00
Evan Cheng adc7093fc1 Use rep/stosl; and Count 0x3; rep/stosb for memset with 4 byte aligned dest. 
and variable value.
Similarly for memcpy.

 2006-03-07 23:29:39 +00:00
Chris Lattner 207291fd1a Two things: 
1. Don't emit debug info, or other llvm.metadata to the .cbe.c file.
2. Mark static ctors/dtors as such, so that bugpoint works on C++ code
   compiled with the new CFE.

Chris Lattner d312f73022 new testcase that should have been added long ago. 
llvm-svn: 26601
 2006-03-07 22:33:00 +00:00
Jim Laskey 313570fb17 Use "llvm.metadata" section for debug globals. Filter out these globals in the 
asm printer.

 2006-03-07 20:53:47 +00:00
Chris Lattner 7b87fd53f9 Fix ConstantMerge/2006-03-07-DontMergeDiffSections.ll, a problem Jim 
hypotheticalized about, where we would incorrectly merge two globals in
different sections.

Jim Laskey 3bad199894 Bitfield support. 
llvm-svn: 26593
 2006-03-07 15:51:33 +00:00
Evan Cheng 0fab08eae3 Don't generate silly matching code like this: 
if (N1.getOpcode() == ISD::ADD &&
     ...)
   if (... &&
       (N1.getNumOperands() == 1 || !isNonImmUse(N1.Val, N10.Val))) &&
       ...)

TableGen knows N1 must have more than one operand.

Nate Begeman 3e3219cc0a This kinda sorta implements "things that have to lead a dispatch group". 
llvm-svn: 26591
 2006-03-07 08:30:27 +00:00
Chris Lattner 675567f77c add some new instructions to the classifier. With this, we correctly insert 
a nop into Freebench/neural, which speeds it up from 136->129s (~5.4%).

Chris Lattner 0c801bd1cf Fix some formatting, when looking for hazards, prefer target nodes over 
things like copyfromreg.

Evan Cheng a4a4ceb478 - Emit subsections_via_symbols for Darwin. 
- Conditionalize Dwarf debugging output (Darwin only for now).

Chris Lattner 9b4ebee871 new regression test 
llvm-svn: 26579
 2006-03-06 23:52:37 +00:00
Chris Lattner 82f2ef20b6 Teach instcombine to increase the alignment of memset/memcpy/memmove when 
the pointer is known to come from either a global variable, alloca or
malloc.  This allows us to compile this:

  P = malloc(28);
  memset(P, 0, 28);

into explicit stores on PPC instead of a memset call.
