2021-03-21Remove dead code for Vita: pc_callbackReiko Asakura1-37/+4
2021-01-23Port to Vita Development SuiteReiko Asakura1-1/+0
2016-11-23Fixed defination of CC_CBXZ collides with other bitsYifan Lu1-1/+3
Fixed incorrect pc value in tdctx_to_actx Fixed ARM32 handling of CC_CBXZ (uses incorrect field in ctx->base) Fixed ARM32 transform_dis_branch incorrectly trashing LR for non-call based jumps Fixed ARM32 make_jump_patch not updated to use new assemble_ctx Added new option SUBSTITUTE_RELAXED to relax the disassembly engine Currently SUBSTITUTE_RELAXED only disables TRANSFORM_DIS_REL_JUMPS so jumps at the beginning of functions are allowed

2015-03-01A number of critical fixes painstakingly discovered in the slowest way possible.comex1-7/+10
2015-02-28Add extra argument to substitute_hook_functions and interpose_imports for ↵comex1-1/+6
use with unhooking. I think we'll need to explicitly record trampoline locations to avoid the possibility of stomping on someone else's stuff if the function was re-patched... Also, document substitute_hook_functions.

2015-02-18Fix hook-function:comex1-44/+31
- Thread stoppage is now complemented by sigaction to catch injected threads (sigaction is not used exclusively because the rest of the program could be trying to use sigaction itself in the meantime - this is a real thing, ask Dolphin) - mprotect is no longer used due to max_protection possibly getting in the way; instead, a copy is created and mapped onto the original.
2015-02-14Trampoline fixes.comex1-29/+29
The transformed code was incorrect because it assumed the pointer it was writing to was where the code would execute, but it was actually 'rewritten_temp'. Changed transform_dis_main to take a pc_trampoline pointer, which also helps the test harness. However, this means that it has to be called after the trampoline has been allocated, while before the trampoline allocation depended on the generated size; this change doesn't bother to use two passes or anything, but just allocates a new code buffer if the maximum possible size isn't available - not the end of the world, since trampoline_ptr will still only be increased by the actual size before the next hook in the series (if any).
2015-02-08Refactor disassembly so x86 works, and add x86 transform-dis.comex1-2/+2
This patch is a monolithic mess, because I was too lazy to do the refactor first (that would require some stash fun, since I wasn't actually sure before doing x86 transform-dis what would be needed). Anyway, the resulting code should be cleaner - less duplication. This breaks ARM/ARM64.
2015-02-03fix ARM64 too, theoreticallycomex1-12/+15

the minimum would be... (and minor build fixes)
