I cannot accept this patch: it breaks qemu-fast with all old libcs. The
good solution is to use a specific sigaction call which directly makes
the sigaction Linux system call.
What about various #ifdefs or bumping up the requirements?
Also, I could not get qemu-fast working with any glibc >=2.3.1 compiled
from pristine sources according to instructions from Linux From Scratch.
Qemu-fast compiles, but doesn't work with glibc >=2.3.1. It does not
compile at all with glibc-2.3.3-cvs with TLS enabled. See my message
"qemu and modern glibc" for changes to qemu that make qemu-fast at least
compile on glibc >=2.3.3-cvs. Please confirm privately that you have
read this message.
The tail of qemu.log is:
----------------
IN:
0x000c625d: repz stos %ax,%es:(%di)
----------------
IN:
0x000c625d: repz stos %ax,%es:(%di)
(repeated infinitely without any OUT, even if I add out_asm to the -d
switch). Plain non-fast qemu works perfectly.
What are known good _pristine_ (not RedHat) glibc versions that are
capable of producing a good qemu-fast binary?
On what distribution does the qemu development happen? What are
binutils/gcc/glibc versions?
