* target-cris: Fix typo in D_LOG() macroAndreas Färber2013-01-241-1/+1
| | | | | | | | | | | It's __VA_ARGS__. Fixes the build with CRIS_[OP_]HELPER_DEBUG defined. Broken since r6338 / 93fcfe39a0383377e647b821c9f165fd927cd4e0 (Convert references to logfile/loglevel to use qemu_log*() macros).

* exec.h cleanupBlue Swirl2011-07-301-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
