Hello,
I've been asked to make Open64's whirl2c and whirl2f work reliably
enough that it is possible to:
1. Translate SPECfp2000 source code into WHIRL
2. Apply preopt and LNO
3. Regenerate source code
4. Compile with GCC on amd64 or i386

Roy Ju from Intel mentioned some time ago that they might have
a cleaned up version of whirl2c that works well. I do not think
it made it into the ORC release.
Has there been any news of this version?
Greg Lindahl said you (LBL+UCB) had already made many improvements to
SGI's whirl2c. I checked wn2c.cxx but I am not familiar enough yet with
the code to understand the improvements.
I downloaded berkeley_upc_translator-2.0.1.tar.gz and compiled it on
Linux/i386 with GCC 3.2.2
Is your whirl2c supposed to work with WHIRL files produced by ORC 2.1?
(Perhaps my environment is not set up correctly.)
$ cat testcase.c
struct foo { int x; int y[3]; } bar;
int main(void)
{
bar.y[1] = 666666;
return 0;
}
$ orcc -fe -keep testcase.c
$ upc_whirl2c testcase.B
### Assertion failure at line 932 of ../../be/whirl2c/ty2c.cxx:
### Compiler Error in file testcase.c during Post LNO Processing phase:
### Unexpected TY_kind (0) in TY2C_translate()
Did you modify the WHIRL?
On a related subject, can I simply feed pre-processed C the gfec binary
to produce a WHIRL file, and then use ORC's preopt and LNO?
