Nguyen Anh Quynh 16f330c37a cs_disasm(): properly resize the cache when count in range [2, INSN_CACHE_SIZE] 2014-10-02 10:09:59 +08:00
Nguyen Anh Quynh 523ca99087 cs_disasm(): make sure cache_size is smaller than INSN_CACHE_SIZE to avoid integer overflow in malloc() 2014-10-01 10:46:37 +08:00
Nguyen Anh Quynh 50eeba2a86 avoid setting instruction cache size to @count when Capstone uses user-customized memory management, which might fail in resource scarce env such as kernel 2014-09-30 13:28:02 +08:00
Nguyen Anh Quynh ac98ca0129 set buffer size for instruction cache in cs_disasm() to @count if @count > 0. this avoids realloc() in cases where @count is pre-determined. thanks Dang Hoang Vu for the idea 2014-09-30 13:17:36 +08:00

Nguyen Anh Quynh 0b690387b3 x86: update core with upstream. this added bunch of new instructions & groups. also updated Python & Java bindings after the core change 2014-08-13 13:01:50 +08:00
Nguyen Anh Quynh 5d8067822b Merge branch 'next' of https://github.com/flyingsymbols/capstone into arm 2014-07-31 15:36:13 +08:00
flyingsymbols 298d413bbc * added a test file to suite for testing invalid and valid instruction sequences
* fixed and added a test for a thumb-2 invalid sequence that was incorrectly allowed before these changes (pop.w with sp argument included)
* fixed and added a test for a blx from thumb to ARM that had its immediate argument incorrect (misaligned)

* eliminated some warnings by explicitly casting so I could turn on
  treat warnings as errors locally

General notes:
*  probably worth turning on treat all warnings as errors in the msvc project files, had a subtle bug that resulted from a missing declaration causing differences in dll and static compilation modes

( code was working incorrectly in dll form because of missing declaration in arch/ARM/ARMMapping.h for new function ARM_blx_to_arm_mode. Something about the linking was confusing ld when making the dll, and the resulting offsets were wonky (e.g. the added ble test would show up as #0x1fc instead of #0x1fe like it should have )

* the invalid pop was being treated as a soft fail which then gets coerced
  to a success because it is != MCDisassembler_Fail in Thumb_getInstruction
  what are the semantics of a soft fail? Maybe we should be able to set up
  whether or not we want a soft fail to be a real fail in the csh struct?

Nguyen Anh Quynh 027afdc179 Change the prototype of the callback in SKIPDATA option. Suggested by Ben Nagy.
Original prototype:
  typedef size_t (*cs_skipdata_cb_t)(const uint8_t *code, uint64_t offset, void* user_data);

Now we add @code_size argument to reflect the size of the input buffer @code.
Also, we change the data type of @offset to size_t because this argument indicates the
distance from currently examining bytes to @code, but not the address of the byte.

  typedef size_t (*cs_skipdata_cb_t)(const uint8_t *code, size_t code_size, size_t offset, void* user_data);
