Bug 19547 – Transcode-0.6.4_pre20030409 ebuild fails with -mfpmath=sse,387 due to improper filter-flags

• Status: RESOLVED WONTFIX
• Product: Gentoo Linux

[Description Steven Robertson 2003-04-18 09:17:00 UTC]

I'm a risky person when it comes to system optimizations (except for anything that 
reduces precision).  As one can assume from the title, I have "-mfpmath=sse,387" 
enabled in my CFLAGS.  For Bug #14920, the code "filter-flags -mfpmath=sse" was 
added to the ebuild.  However, this code removes /only/ the literal string given after 
filter-flags, leaving me with a ",387" hanging loose in my CFLAGS.  Ebuild quits at the 
configure stage because GCC won't produce executable binaries or some such. 
 
To fix: 
 
Add a "filter-flags -mfpmath=sse,387" to the filter-flags lines at the ebuild. 
 
Thanks, Gentoo Team! 

Reproducible: Always
Steps to Reproduce:
1.  Emerge transcode-0.6.4_pre20030409 with -mfpmath=sse,387 in CFLAGS.

Expected Results:

[Comment 1 Jonathan Bastien-FiIiatrault 2003-04-20 17:21:13 UTC]

Also observed for 0.6.3

[Comment 2 Steven Robertson 2003-05-09 20:33:12 UTC]

Observed with 0.6.4 as well. 

[Comment 3 Georgi Georgiev 2003-05-25 11:50:35 UTC]

Which reminds me that if one has -msse or similar in their flags, the filter-flags won't catch it at all. Maybe the flag-o-matic should be taught about those -m aliases.

ooops, my bad... obviously -msse does NOT enable -mfpmath=sse

sse,387 is dangerous and broken
