This was strange to read, because I've definitely noticed it with 3.4.3.
Interestingly, it seems to be only g++, rather than gcc, that has the problem:
plg2=; cat g7.c
register void *tp __asm__("%g7");
void set_tp() {
tp = 0;
}
plg2=; gcc -S g7.c
plg2=; grep register g7.s
.register %g7, tp
plg2=; g++ -S g7.c
plg2=; grep register g7.s
.register %g7, %g7
plg2=; gcc -v
