Revision: 1.7
Committed: 2005-02-27T21:52:06Z (19 years, 9 months ago) by gbeauche
Content type: text/plain
Branch: MAIN
Changes since 1.6: +1 -0 lines
Log Message: 
Fix native Linux/ppc with recent enough glibc that supports TLS; r2 is used
in that case. Tell me if I broke other arches, e.g. r13 is no longer saved
in Video and Ethernet stubs, though it seems to be OK.

Colateral feature: SheepShaver should now run on Linux/ppc64 with relevant
32-bit runtime. Native Linux/ppc64 support is harder as low mem globals are
32-bit in mind and e.g. the TLS register there is %r13, %r2 is the TOC
(PowerOpen/AIX ABI)
