2011-05-22Delete unused tb_invalidate_page_rangeBlue Swirl
tb_invalidate_page_range() was intended to be used to invalidate an area of a TB which the guest explicitly flushes from i-cache. However, QEMU detects writes to code areas where TBs have been generated, so his has never been useful. Delete the function, adjust callers.

2011-04-20Remove unused function parameters from gen_pc_load and rename the functionStefan Weil
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).

2011-04-10Fix conversions from pointer to tcg_target_longStefan Weil
tcg_gen_exit_tb takes a parameter of type tcg_target_long, so the type casts of pointer to long should be replaced by type casts of pointer to tcg_target_long (suggested by Blue Swirl). These changes are needed for build environments where sizeof(long) != sizeof(void *), especially for w64.

2010-12-28target-sparc: fix udiv(cc) and sdiv(cc)Aurelien Jarno
Since commit 5a4bb580cdb10b066f9fd67658b31cac4a4ea5e5, Xorg crashes on a Debian Etch image. The commit itself is fine, but it triggers a bug due to wrong computation of flags for udiv(cc) and sdiv(cc). This patch only compute cc_src2 for the cc version of udiv/sdiv. It also moves the update of cc_dst and cc_op to the helper, as it is faster doing it here when there is already an helper.

Sparc64 alternate space load/store helpers expect 8 bit ASI value, while wrasi implementation sign-extends ASI operand causing for example 0x80 to appear as 0xFFFFFF80.

2009-09-12Fix sys-queue.h conflict for goodBlue Swirl
Problem: Our file sys-queue.h is a copy of the BSD file, but there are some additions and it's not entirely compatible. Because of that, there have been conflicts with system headers on BSD systems. Some hacks have been introduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896, f40d753718c72693c5f520f0d9899f6e50395e94, 96555a96d724016e13190b28cffa3bc929ac60dc and 3990d09adf4463eca200ad964cc55643c33feb50 but the fixes were fragile. Solution: Avoid the conflict entirely by renaming the functions and the file. Revert the previous hacks. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-08-04Sparc64: replace tsptr with helper routineIgor Kovalenko
tl and tsptr of members sparc64 cpu state must be changed simultaneously to keep trap state window in sync with current trap level. Currently translation of store to tl does not change tsptr, which leads to corrupt trap state on corresponding trap level. This patch removes tsptr from sparc64 cpu state and replaces all uses with call to helper routine. Changes v0->v1: - reimplemented helper routine with tcg generator - on cpu reset trap type and pstate are populated with power-on reset values, including tl=maxtl Signed-off-by: igor.v.kovalenko@gmail.com Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
