Add more OPC values, and tgen_arithr. Use the later throughout. Note that normal reg/reg arithmetic now uses the Gv,Ev opcode form instead of the Ev,Gv opcode form used previously. Both forms disassemble properly, and so there's no visible change when diffing log files before and after the change. This change makes the operand ordering within the output routines more natural, and avoids the need to define an OPC_ARITH_EvGv since a read-modify-write with memory is not needed within TCG.

In oneshot mode, the delta needs to come from the TimerLoad register, not the maximum limit. Signed-off-by: NRabin Vincent <rabin@rab.in> Signed-off-by: NAurelien Jarno <aurelien@aurel32.net>
-
由 Rabin Vincent 提交于
Reload the timer when TimerControl is written, if the timer is to be enabled. Otherwise, if an earlier write to TimerLoad was done while periodic mode was not set, s->delta may incorrectly still have the value of the maximum limit instead of the value written to TimerLoad. This problem is evident on versatileap on current linux-next, which enables TIMER_CTRL_32BIT before writing to TimerLoad and then enabling periodic mode and starting the timer. This causes the first periodic tick to be scheduled to occur after 0xffffffff periods, leading to a perceived hang while the kernel waits for the first timer tick.

Use int32 types instead of target_ulong when computing ICC. This simplifies the generated code for 32-bit host and 64-bit guest. Use the same simplified expressions for ICC as were already used for XCC in carry flag generation. Simplify the ADD carry generation to not consider a possible carry-in. Use the more complex carry computation for ADDX only. Use the same carry algorithm for the XCC result of ADDX. Similarly for SUB/SUBX. Use the ADD carry generation functions for TADD/TADDTV. Similarly for SUB and TSUB/TSUBTV. Tidy the code with respect to CODING_STYLE. Signed-off-by: NRichard Henderson <rth@twiddle.net> Signed-off-by: NBlue Swirl <blauwirbel@gmail.com>

This patch enhances the algorithm which finds the correct settings for SDL. For cross compilations (when cross_prefix is set), it looks for sdl-config with cross prefix. Here is the complete search order: $(cross_prefix}pkg-config (old, only used for cross compilation) ${cross_prefix}sdl_config (new, only used for cross compilation) pkg-config (old, needs PATH) sdl-config (old, needs PATH) Cross SDL packages (or the user) now can simply set a link (for example /usr/bin/i586-mingw32msvc-sdl-config -> /usr/i586-mingw32msvc/bin/sdl-config) which allows cross compilations without PATH modifications. Without the patch, configure and make (which calls configure) typically need a non-standard PATH. Failing to set this special PATH results in broken builds.
