2012-10-07target-sparc: Make CPU_LOG_INT useful by defaultRichard Henderson2-11/+4
No need for ifdefs when the log mask does just as well. No need to print pc/npc when we're dumping the whole cpu state. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-07target-sparc: Tidy cpu_dump_stateRichard Henderson1-4/+3

2012-10-07tcg: Remove redundant pointer from TCGContextStefan Weil2-3/+1
The pointer entry 'temps' always refers to the array entry 'static_temps'. Removing the pointer and renaming 'static_temps' to 'temps' reduces the size of TCGContext (4 or 8 byte) and allows better code generation.

2012-10-06qemu-barrier: Fix compilation on i386 hostsStefan Weil1-0/+2
Commit 610b823ef66b993660f1ab1447a769f190e4f3b3 uses QEMU_GNUC_PREREQ on i386 hosts. That macro is defined in qemu-common.h which is not always included before qemu-barrier.h, so compilation on i386 hosts was broken.

2012-10-06tcg: Add tcg_high_condRichard Henderson2-15/+19
The table that was recently added for hppa is generally usable. And with the renumbering of the TCG_COND constants it's not too difficult to compute rather than have a table. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2012-10-06tcg: Add TCG_COND_NEVER, TCG_COND_ALWAYSRichard Henderson11-41/+102
There are several cases that can be handled easier inside both translators and code generators if we have out-of-band values for conditions.

2012-10-06tcg: remove obsolete jmp opAurelien Jarno13-71/+1

2012-10-05target-arm: convert sar, shl and shr helpers to TCGAurelien Jarno3-33/+43
Now that the movcond TCG op is available, it's possible to replace shl and shr helpers by TCG code. The code generated by TCG is slightly longer than the code generated by GCC for the helper but is still worth it as this avoid all the consequences of using an helper: globals saved back to memory, no possible optimization, call overhead, etc. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-10-05target-arm: convert add_cc and sub_cc helpers to TCGAurelien Jarno3-40/+48
Now that the setcond TCG op is available, it's possible to replace add_cc and sub_cc helpers by TCG code. The code generated by TCG is actually very close to the one generated by GCC for the helper, and this avoid all the consequences of using an helper: globals saved back to memory, no possible optimization, call overhead, etc. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-10-05target-arm: use globals for CC flagsAurelien Jarno1-81/+46

2012-10-05target-arm: Reinstate display of VFP registers in cpu_dump_statePeter Maydell1-26/+16
Reinstate the display of VFP registers in cpu_dump_state(), if the CPU has them (this code had been #if 0'd out a for a long time). We drop the attempt ot display the values as floating point, since this makes assumptions about the host 'float' and 'double' formats and is not done by eg the i386 cpu_dump_state(). This display is gated on the CPU_DUMP_FPU flag, as for x86. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-10-05cpu_dump_state: move DUMP_FPU and DUMP_CCOP flags from x86-only to genericPeter Maydell10-34/+15
Move the DUMP_FPU and DUMP_CCOP flags for cpu_dump_state() from being x86-specific flags to being generic ones. This allows us to drop some TARGET_I386 ifdefs in various places, and means that we can (potentially) be more consistent across architectures about which monitor commands or debug abort printouts include FPU register contents and info about QEMU's condition-code optimisations.
