* Speeding up Linux kernel compiles using -pipe? @ 2003-06-25 4:22 Shawn Starr 2003-06-25 4:55 ` Sam Ravnborg 2003-06-25 5:29 ` Anton Blanchard 0 siblings, 2 replies; 5+ messages in thread From: Shawn Starr @ 2003-06-25 4:22 UTC (permalink / raw) To: linux-kernel Why aren't we using -pipe? It can significantly speed up compiles by not writing temp files (intermediate files). I don't see harm in adding this? What do you all think?

Most architectures already uses -pipe - see arch/*/Makefile: [sam@mars v2.5]$ ls arch/*/Makefile | xargs grep -l -- -pipe | wc -l 17 [sam@mars v2.5]$ ls arch/*/Makefile | wc -l 21 Sam ^ permalink raw reply [flat|nested] 5+ messages in thread

Unless something has changed recently, -pipe is actually a slowdown. -Mike ^ permalink raw reply [flat|nested] 5+ messages in thread
