2013-04-26PPC: Fix compile with profiling enabledAlexander Graf1-0/+1
When using profiling, we rely on profile_getclock() being available at our disposal. Somehow that function got moved from an indirect include we used to have in translate-init.c, so that we were now left not properly compiling anymore. Add an explicit include to timer.h which defines profile_getclock, so that we can compile again. Signed-off-by: Alexander Graf <agraf@suse.de>

2013-03-22tcg: Fix occasional TCG broken problem when ldst optimization enabledYeongkyoon Lee1-2/+2
is_tcg_gen_code() checks the upper limit of TCG generated code range wrong, so that TCG could get broken occasionally only when CONFIG_QEMU_LDST_OPTIMIZATION enabled. The reason is code_gen_buffer_max_size does not cover the upper range up to (TCG_MAX_OP_SIZE * OPC_BUF_SIZE), thus code_gen_buffer_max_size should be modified to code_gen_buffer_size.

2013-03-03Handle CPU interrupts by inline checking of a flagPeter Maydell1-2/+2
Fix some of the nasty TCG race conditions and crashes by implementing cpu_exit() as setting a flag which is checked at the start of each TB. This avoids crashes if a thread or signal handler calls cpu_exit() while the execution thread is itself modifying the TB graph (which may happen in system emulation mode as well as in linux-user mode with a multithreaded guest binary). This fixes the crashes seen in LP:668799; however there are another class of crashes described in LP:1098729 which stem from the fact that in linux-user with a multithreaded guest all threads will use and modify the same global TCG date structures (including the generated code buffer) without any kind of locking. This means that multithreaded guest binaries are still in the "unsupported" category.

2012-04-07w64: Fix data type of tb_next and other variables used for host addressesStefan Weil1-3/+3
QEMU host addresses must use uintptr_t to be portable for hosts with an unusual size of long (w64). tb_jmp_offset is an uint16_t value, therefore the local variable offset in function tb_set_jmp_target was changed from unsigned long to uint16_t. The type cast to long in function tb_add_jump now also uses uintptr_t. For the bit operation used here, the signedness of the type cast does not matter. Some remaining unsigned long values are either only used for ARM assembler code or will be fixed in a later patch for PPC. v2: Fix signature of tb_find_pc in exec.c, too (hint from Blue Swirl, thanks). There remain lots of other long / unsigned long in exec.c which must be replaced by uintptr_t. This will be done in a separate patch. Here only one of these type casts is fixed. v3: Also fix signature of page_unprotect. Signed-off-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-04-20Remove unused function parameters from gen_pc_load and rename the functionStefan Weil1-1/+1
Function gen_pc_load was introduced in commit d2856f1ad4c259e5766847c49acbb4e390731bd4. The only reason for parameter searched_pc was a debug statement in target-i386/translate.c. Parameter puc was needed by target-sparc until commit d7da2a10402f1644128b66414ca8f86bdea9ae7c. Remove searched_pc from the debug statement and remove both parameters from the parameter list of gen_pc_load. As the function name gen_pc_load was also misleading, it is now called restore_state_to_opc. This new name was suggested by Peter Maydell, thanks. v2: Remove last parameter, too, and rename the function. v3: Fix [] typo in target-arm/translate.c. Fix wrong SHA1 object name in commit message (copy+paste error).
