Hello

I have an amd k6 233, Redhat 6.0 and kernel 2.2.13,
just 2 days ago I have installed pgcc 2.95.1 (before I used pgcc 1.1.1).
Than I have done some test:
1) bladeenc
  compiling codec.c with an optimaztion higher than -O1 gives a
  a working but bad encoder (but this is known even whith older
  versions of pgcc and egcs).
  compiling the rest of it (not the codec) whith -funroll-all-loops
  makes bladeenc crash (whith pgcc 1.1.1 it didn't).
  compiling whith -ffast-math gives a slow and bad working encoder
  compiling bladeenc whithout -funroll-all-loops gives a fast
well-working
  bladeenc (faster the one compiled with pgcc 1.1.1 with
-funroll-all-loops
  enabled). So the flags I used for bladeenc :
  -O6 -malign-functions=2 -malign-jumps=2 -mk6 -march=k6
2) XFree 3.3.5
  compiling with pgcc 2.95.1 and with
  -O6 -fno-strength-reduce -malign-functions=2 -malign-jumps=2 -mk6
-march=k6 
  gives a not working X server (it crashes on startup),
  compiling whith pgcc 1.1.1 and with
  -O6 -fno-strength-reduce -malign-functions=2 -malign-jumps=2 -mamdk6
-march=amdk6 -funroll-all-loops
  gives a very fast and perfect Xserver (I have used it for mounths
without a crash).
3) Mozilla M10
  compiling with pgcc 2.95.1 and with 
  -O6 -fno-strength-reduce -malign-functions=2 -malign-jumps=2 -mk6
-march=k6
  gives a not working executable
  compiling with pgcc 1.1.1 there is no way to get the build finished
(due
  to compiler internal errors)
4) WindowMaker 0.61.1
  The one compiled with pgcc 2.95.1 is much faster than the one compiled
with
  pgcc 1.1.1.
5) The -fno-strength-reduce flag
  The problems that there were in pgcc 1.1.1 with the 
-fno-strength-reduce flags
  seem to be resolved in pgcc 2.95.1

My Conclusions:
I find pgcc 1.1.1 much more reliable even if a little bit slower.

I hope you can tell me that I'm missing some "magic" flag that will
make me compile Xfree and mozilla perfectly.
If not I hope that this mail will help pgcc develop in some ways.
Bye
         Fox

P.S.
Sorry for my bad english
