Reid Spencer 5dd0111188 Add a brief description for the tblgen program. More detail is needed but 
the current author is not the person to provide it. Now that the file
exists, perhaps others will chime in and embellish.

Reid Spencer a9355fa5d8 Update the documentation for llvm2cpp after the -gen-* options were added.

Reid Spencer de2daad0ac Major reorganization and extension of the code. The diff on this will be a 
mess as functions were moved around into a better ordering. The code was
extended to provide various -gen-* options to better control what the
generated output should be. Currently it is possible to generate entire
modules (three different ways), functions, global variables, and types.

Reid Spencer 9fef163d19 Make the getNamedFunction and getNamedGlobal methods be const. They don't 
change the module in any way and we should enforce that.

 2006-05-30 23:34:30 +00:00
Reid Spencer b5ddb66ce0 1. No need to thwart this test with an environment variable. Turning it off 
is the default and handled by the makefile system and runtest
2. Redirect stderr of llvm-as and llvm2cpp so that warning messages about
   instrinsics don't cause Tcl to report the run as failed.

Evan Cheng f21045a5cd Somehow I lost a condition when I was shuffling some code around. Anyway, 
only transform a shufps to pshufd when the first two operands are the same.

 2006-05-30 21:29:15 +00:00
Chris Lattner b9342afa56 Always reserve space for 8 spilled GPRs. GCC apparently assumes that this 
space will be available, even if the callee isn't varargs.

Reid Spencer c3b9370754 llvm2cpp is ready to be compiled so add it to the makefile, but make it 
optional.

Reid Spencer 30945ca559 Fix more bugs. This version now passes all of the Feature test except for 
a floating point conversion problem with NAN in intrinsics.ll. llvm2cpp
makes an attempt to provide the correct conversion, based on the
implementation in the CBackend writer, but it doesn't get NAN correct.

 2006-05-30 19:56:31 +00:00
Reid Spencer 82ebabafde Provide a simpler interface for getting a ConstantArray from a character 
string. Instead of specifying the length, just specify whether the user
wants a terminating null or not. The default is "true" to retain the same
behavior as previously provided by this function.

Evan Cheng d12c97d23a Make sure the register pressure reduction schedulers work for non-uniform 
latency targets, e.g. PPC32.

Evan Cheng 61e9f0d680 When a priority_queue is empty, the behavior of top() operator is 
non-deterministic. Returns NULL when it's empty!

Reid Spencer b0cffafb59 Undo a patch that breaks llvm-as because the warning message is written to 
stdout when the output of llvm-as is also written to stdout. We'll have to
fix tcl some other way.

llvm-svn: 28557
 2006-05-30 16:34:59 +00:00
Reid Spencer b5c64fc3b6 Write the WARNING message to cout instead of cerr. Writing to cerr causes 
Tcl to claim that the program had an error and thus produces errors in
the dejagnu testing when its really just a warning.

Reid Spencer 37cf1765ed Fix many small bugs in llvm2cpp. This patch gets llvm2cpp working with 
everything except PHI nodes and one odd recurse/opaque type situation.
PHI nodes forward reference INSTRUCTIONS (aaaaaaaahhhhhhh!) :)

Reid Spencer 84504f215b Properly document the second form of ConstArray::get() 
llvm-svn: 28553
 2006-05-30 08:26:13 +00:00
Reid Spencer 6f61453ff8 Adjust the interface to ConstantArray::get. The previous 
implementation always added a null byte to the end of the string. It turns
out that this is not always wanted. By adding a length parameter we preserve
this behavior when length==0 (default value) but also allow other lengths
(not null terminated) to be created.

Evan Cheng 734e1e241b A addressing mode folding enhancement: 
Fold c2 in (x << c1) | c2 where (c2 < c1)
e.g.
int test(int x) {
  return (x << 3) + 7;
}

This can be codegen'd as:
leal 7(,%eax,8), %eax

Reid Spencer c267698f23 First complete version of llvm2cpp that doesn't crash on any of the Feature 
tests. The output in a few cases still doesn't compile, however.
