Description Grzegorz Dubicki 2004-07-25 06:49:03 UTC 
Emerge allegro-4.1.14 fails in compilation phase due to CFLAG problem.

It doesn't compile with:

* CFLAGS="-march=athlon-xp -O3 -msse -mmmx -m3dnow -momit-leaf-frame-pointer -fomit-frame-pointer -ftracer -ffast-math -fforce-addr -mno-push-args -pipe -s -fpic"

or

* same as above without -fpic (although it shouldn't matter as this flag is filtered in the ebuild)

or 

* CFLAGS="-march=athlon-xp -Os -fomit-frame-pointer -momit-leaf-frame-pointer -ffast-math -fforce-addr -mno-push-args -pipe -s -fpic"

or

* same as above without -fpic

...but it *DOES* compile with

* CFLAGS="-march=athlon-xp -mtune=athlon-xp -O2 -pipe".

Reproducible: Always
Steps to Reproduce:
1. set CFLAGS to one of the mentioned above values
2. ACCEPT_KEYWORDS="~x86" emerge -v =media-libs/allegro-4.1.14
Actual Results:

---

That's the error message with the first CFLAGS values set (CFLAGS="-
march=athlon-xp -O3 -msse -mmmx -m3dnow -momit-leaf-frame-pointer -fomit-frame-
pointer -ftracer -ffast-math -fforce-addr -mno-push-args -pipe -s -fpic").

With another non-working CFLAG value the only difference, if I recall correctly, 
is that there is only *one* "./tests/afinfo.c:258: error: can't find a register 
in class `BREG' while reloading `asm'" line.

Expected Results:  
Emerge allegro-4.1.14 should finish without problems.

Can you isolate which flag is causing the issue please?  I'll add it to the flag filtering.
Comment 2 Grzegorz Dubicki 2004-07-26 05:23:29 UTC 
Ok, I've tried several combination of CFLAGS using both gcc 3.3.3 and 3.4.1 and for both of them the problem flag seems to be "-fpic" (lowercase).

("Prove": even this hardcore setting works - it compiles cleanly, that is (note the "-fno-pic" near the end:

CFLAGS="-O3 -march=athlon-xp -mtune=athlon-xp -msse -mmmx -m3dnow -momit-leaf-frame-pointer -fomit-frame-pointer -funroll-loops -ftracer -ffast-math -fprefetch-loop-arrays -freduce-all-givs -finline-limit=600 -mfpmath=387 -pipe -fweb -fPIC -fno-pic -s")

*** Concluding: I would propose filtering out the "-fpic" (lowercase) flag in the ebuild.
