Modified files:
sys/amd64/ia32 ia32_sigtramp.S
Log:
Stop reloading %fs and %gs, since it causes the base address from
GDT to be loaded into FS.base and GS.base, these values of course
are not the values set by sysarch() with I386_SET_FSBASE and
I386_SET_GSBASE, the change fixed a crash for 32bit libthr after
signal handler returned and normal code is accessing thread pointer,
for example: movl %gs:8, %eax.
