Summary: Still required to compile libGL without PIC on i386?
Product: xorg
Version: CVS_head
Platform: Other
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Lib/GLX

prelink: /usr/lib/xscreensaver/spheremonics: shared
library /usr/lib/libGL.so.1.2 appears possibly non-PIC and contains conflicts.
Symbol offset: 413205fc
It turns out that shared libGL is still built without PIC on i386.
linux.cf:
[...]
/*
* Build shared libGL and the DRI modules without -fPIC on some architectures.
* This improves performance.
*/
#if BuildXF86DRI
# if defined(i386Architecture)
# define BuildLibGlxWithoutPIC YES
# endif
#endif

320. Build shared libGL and DRI client modules on Linux without PIC for
performance reasons.
I finally did some testing with PIC/non-PIC with viewperf 7.1.1:
(Radeon 7500, AMD64 1.6 GHz, 1 GB Memory, 32bit)
non-PIC PIC
3dsmax-02 3.047 3.049
drv-09 3.928 3.282
dx-08 19.06 19.00
light-06 3.433 3.373
proe-02 2.328 2.319
ugs-03 1.492 1.434
I can't see any significant differences. Therefore I propose to enable PIC
for libGL again. What do you think? Maybe gcc has improved a *lot* in the
last 3 years, so this is no longer required?
