[LLVMdev] testing instruction selection
...om the DAGS as opposed to
LLVM assembler bitcode.
It should also be possible to compile a C file or LLVM assembler bitcode
file and save off the DAGS ascii file.
Believe it or not, they had this over 30 years ago with the PQCC
(Production Quality Compiler Compiler ) project at Carnegie Mellon.
Intermetrics where I worked had a commercial version of this and later
Tartan Laboratories.

Any phase of the compiler had an ascii representation that could be
parsed into binary stuctures and then submitted to that phase and
optionally propagated to later phases. You could...

It's kind of troubling that you can't create test cases that start with
DAG as opposed to bitcode .ll.
It's very tedious sometimes to go through and make sure that you have
really tested all your patterns and sometimes the compiler changes and
it stops generating those patterns but may resume generating them later.
So if you make a change at a time when it's not generating

Lets try this push again.. 2.5.1p2 bugs left.
Things that are still outstanding:
1) Solaris/Redhat/HPUX session.c patch. I've not seen a ya or na on

2) Odd Redhat/Debian scp/ssh issues. .. I'm baffled, and I can't
replicate the bug. Nor have I seen anything remotely like it reported.
3) SCO.. Is it happy yet for compiling? =)
Completed:
1) mdoc2man.pl .. Commited into
