Reid Spencer 5cb722f320 Don't build tblgen with -pedantic or -Wno-long-long 
llvm-svn: 28638
 2006-06-01 18:20:23 +00:00
Evan Cheng cc8c0233b6 Can't trust NodeDepth when checking for possibility of load folding creating 
a cycle. This increase the search space and will increase compile time (in
practice it appears to be small, e.g. 176.gcc goes from 62 sec to 65 sec)
that will be addressed later.

Evan Cheng 07a4e5ceb1 Fixed a really ugly bug. The TableGen'd isel is not freeing the "inflight set" 
correctly. That is causing non-deterministic behavior (and possibly preventing
some load folding from happening).

Chris Lattner aa2372562e Patches to make the LLVM sources more -pedantic clean. Patch provided 
by Anton Korobeynikov!  This is a step towards closing PR786.

 2006-05-24 17:04:05 +00:00
Evan Cheng 886e8f35aa Now that iPTR is a fully resolved type. We end up losing the type check for 
patterns that look like this:

def : Pat<(i32 (X86Wrapper tconstpool  :$dst)), (MOV32ri tconstpool  :$dst)>;

InsertOneTypeCheck should copy the type from the resolved pattern to the
unresolved one as long as there types are different.

represent pointer type.

Evan Cheng 32982836b6 Watch out for the following case: 
1. Use expects a chain output.
2. Node is expanded into multiple target ops.
3. One of the inner node produces a chain, the outer most one doesn't.

 2006-04-28 18:54:11 +00:00
Evan Cheng 54acf6eddc When isel'ing a node, mark its operands "InFlight" before selecting them. These 
nodes should not be folded into other nodes.
This fixes the miscompilation of PR 749.
Temporarily under flag control.

Nate Begeman 4ca2ea5b43 JumpTable support! What this represents is working asm and jit support for 
x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.

Reid Spencer 5e6f97b7c9 Don't require the "dot" program if -flat option is given, and don't produce 
any of the fancy graphs or other output. Just produce the flat, makefile
style output on stdout.
