My gcc 2.95.3 manual says:
-pipe Use pipes rather than temporary files for communi-
cation between the various stages of compilation.
This fails to work on some systems where the assem-
bler cannot read from a pipe; but the GNU assembler
has no trouble.
so it looks like we can't use it on all platforms without testing. I
will enable it for linux. Do people want to test other platforms?

Let me test BSD/OS now that you mention it. :-) -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073

I saw your message that it was disabled for all builds (I assume you meant "all", not "all BSDs"), but for the sake of completeness: $ uname -a OSF1 hostname V4.0 1229 alpha $ cc -pipe main.c ld: -pipe: Unknown flag ld: Usage: ld [options] file [...] $ gcc -pipe main.c as: Error: no source, object or ucode file specified main.c:46: output pipe has been closed Regards, Philip Yarra.

It was only enabled on BSD's in the code, so I just removed that. It didn't exist in any other builds. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073

I >will enable it for linux. Do people want to test other platforms? It should work on any platform that uses the GNU tools, so that means *BSD is in the same boat as Linux. Does it really speed compilation though? I saw somewhere that it didn't make much difference and might even hurt sometimes. -- The opinions expressed in this message are mine, not those of Caltech, JPL, NASA, or the US Government.
