Apparently not :-)
I just checked if it still applies, and it doesn't. Checking why I ran
into the following strangeness in target-ppc/translate.c:gen_goto_tb()
which appeared during the TCG migration:
..
if ((tb->pc & TARGET_PAGE_MASK) == (dest & TARGET_PAGE_MASK) &&
!ctx->singlestep_enabled) {
..
} else {
gen_set_T1(dest);
#if defined(TARGET_PPC64)
if (ctx->sf_mode)
gen_op_b_T1_64();
else
#endif
gen_op_b_T1();
if (ctx->singlestep_enabled)
gen_op_debug()
}
It seems to me that the second if (ctx->singlestep_enabled) is
rendundant.
I'll see if I can find some time to see if the patch is still needed
and if so, update it to the current HEAD.
Thanks
Marius
