2013-03-12cpu: Move halted and interrupt_request fields to CPUStateAndreas Färber1-1/+3
Both fields are used in VMState, thus need to be moved together. Explicitly zero them on reset since they were located before breakpoints. Pass PowerPCCPU to kvmppc_handle_halt(). Signed-off-by: Andreas Färber <afaerber@suse.de>

Refactor common code around calls to cpu_restore_state(). tb_find_pc() has now no external users, make it static. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-24target-arm: Remove out of date FIXME regarding saturating arithmeticPeter Maydell1-2/+0
Remove an out of date FIXME regarding the saturating arithmetic helpers: we now do pass a pointer to CPUARMState to these helpers, and since the AREG0 changes went in there is no difference between helper.c and op_helper.c and therefore no point in moving the functions.

2012-10-05target-arm: convert sar, shl and shr helpers to TCGAurelien Jarno1-24/+0
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>

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>

2011-07-30exec.h cleanupBlue Swirl1-2/+7
Move softmmu_exec.h include directives from target-*/exec.h to target-*/op_helper.c. Move also various other stuff only used in op_helper.c there. Define global env in dyngen-exec.h. For i386, move wrappers for segment and FPU helpers from user-exec.c to op_helper.c. Implement raise_exception_err_env() to handle dynamic CPUState. Move the function declarations to cpu.h since they can be used outside of op_helper.c context. LM32, s390x, UniCore32: remove unused cpu_halted(), regs_to_env() and env_to_regs(). ARM: make raise_exception() static. Convert #include "exec.h" to #include "cpu.h" #include "dyngen-exec.h" and remove now unused target-*/exec.h. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

The neon_trn_u8, neon_trn_u16, neon_unzip_u8, neon_zip_u8 and neon_zip_u16 helpers used fixed registers to return values. This patch replaces that with TCG code, so T0/T1 is no longer directly used by the helper functions. Bugs in the gen_neon_unzip register load code were also fixed.

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori1-1/+1
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.
