With TCG_OPF_COND_BRANCH, we extended the lifetimes of globals across extended basic blocks. This means that the liveness computed in pass 1 does not kill globals in the same way as normal temps. Introduce TYPE_EBB to match this lifetime, so that we get correct register allocation for the temps that we introduce during the indirect lowering pass.

Do not force exit within qemu_set_log; return bool and pass an Error value back up the stack as per usual. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20220417183019.755276-5-richard.henderson@linaro.org>

Per the recommendations in qapi/error.h, return false on failure. Use the return value in the monitor, the only place we aren't already passing error_fatal or error_abort.

2022-04-20target/hexagon: Remove qemu_set_log in hexagon_translate_initRichard Henderson
This code appears to be trying to make sure there is a logfile. But that's already true -- the logfile will either be set by -D, or will be stderr. In either case, not appropriate here.

2022-04-20util/log: Drop manual log bufferingRichard Henderson
This buffering was introduced during the Paleozoic: 9fa3e853531. There has never been an explanation as to why we may not allow glibc to allocate the file buffer itself. We certainly have many other uses of mmap and malloc during user-only startup, so presumably whatever the issue was, it has been fixed during the preceeding 18 years.
