| | | | | | | | | In theory this would re-enable usage of QEMU on an armv4 host. Whether this is worthwhile is debatable -- we've been unconditionally issuing the armv5t BX instruction in the prologue since 2011 without complaint. Possibly we should simply require an armv6 host.

* tb-hash: improve tb_jmp_cache hash function in user modeEmilio G. Cota2017-06-051-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Optimizations to cross-page chaining and indirect branches make performance more sensitive to the hit rate of tb_jmp_cache. The constraint of reserving some bits for the page number lowers the achievable quality of the hashing function. However, user-mode does not have this requirement. Thus, with this change we use for user-mode a hashing function that is both faster and of better quality than the previous one.

| | | | | | | | | | | | | | | | | | Instead of exporting goto_ptr directly to TCG frontends, export tcg_gen_lookup_and_goto_ptr(), which calls goto_ptr with the pointer returned by the lookup_tb_ptr() helper. This is the only use case we have for goto_ptr and lookup_tb_ptr, so having this function is very convenient. Furthermore, it trivially allows us to avoid calling the lookup helper if goto_ptr is not implemented by the backend. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Emilio G.

For example, commit 3282eca for blockdev-snapshot re-added the extra "options" layer which had been cleaned up in commit 0153d2f. This clears up all regressions identified over the range 02b351d..bd6092e: https://lists.gnu.org/archive/html/qemu-devel/2017-05/msg05127.html as well as a cleanup to x-blockdev-remove-medium to prefer 'id' over 'device' (matching the cleanup for 'eject').

The only mismatch between curses(3) and ncurses is the lack of curses_version() in the NetBSD version.
