Ole André Vadla Ravnås 4c6bc81c79 Revert "Mark cs_* as thread local to avoid race condition in multithreads" (#1933)
Having per-thread memory allocation routines is a major change in
behavior that likely broke a lot of applications.

This reverts commit bdab89496e.

Wu ChenXu c0e1839d5c Merge pull request #1907 from FinnWilkinson/AArch64-Armv9.2-update 2022-10-06 17:27:20 +08:00
Finn Wilkinson 6d5a3b1a44 Updated AArch64 Instruction Printer to support new Armv9.2 instructions.
Implemented new functions present in LLVM 14.0.5 for any new instruction
type in Armv9.2; mainly SME / Matrix printing functions.

New set_sme_index function added (called from AArch64GenAsmWriter.inc)
to correctly add operands to new sme_index operand type. Doing_SME_Index
bool added to cs_struct to indicate when operands should be added to
sme_index type.

Functionality added to support SMSTART/SMSTOP aliases.

Wolfgang Schwotzer 37b8ecbb41 [M680X] Fix #1483: errors logged to stderr, using abort (2) (#1489)
- This is not suitable for an application framework
  especially for kernel code.
- All these error conditions do not occur under normal conditions.
  They only can occur if a maintainer (in the future) would make
  inappropriate changes to the M680X code base.
- Added CS_ASSERT macro which allows to use assertions when debugging
  by defining CAPSTONE_DEBUG.
- Updated compiler documenation

Travis Finkenauer 292116bd0d Declare global arch arrays with contents (next branch) (#1186)
* Declare global arch arrays with contents (#1171)

This eliminates the need for archs_enable() and eliminates the racey
initialization.

This makes the architecture-specific init and option functions
non-static so that they may be called from a different file.

* Add cs_arch_disallowed_mode_mask global

mips: CS_MODE_MIPS32R6 implies CS_MODE_32

Cherry-pick 8998a3a1:
ppc: fix endian check (#1029)
Fixes bug where endianness could not be set for ppc.

Remove `big_endian` field of `cs_struct`.
Added a helper macro `MODE_IS_BIG_ENDIAN()` to check if
`CS_MODE_BIG_ENDIAN` is set.

Refactored `cs_open()` check for valid mode out of arch-specific code
into arch-independent code. Also added a valid mode check to
`cs_option()`.  The checks use a new global array
`cs_arch_disallowed_mode_mask[]`.

* Make global arrays static

Make all_arch uint32_t to guarantee a certain number of bits (with
adequate room for growth).

Travis Finkenauer de99147c73 ppc: fix endian check (#1029)
* Remove `big_endian` field of `cs_struct`

Added a helper macro `MODE_IS_BIG_ENDIAN()` to check if
`CS_MODE_BIG_ENDIAN` is set.

Refactored `cs_open()` check for valid mode out of arch-specific code
into arch-independent code. Also added a valid mode check to
`cs_option()`.  The checks use a new global array
`arch_disallowed_mode_mask[]`, which is initialized in the arch-specific
`*_enable()` functions.

Fixes bug where endianness could not be set for ppc.
