Changelog:
-------------------------------------
2.40
Switch fixes for negative cases and optimisations.
Removed BND prefix from JCXZ instruction group to fix encoding issues in 16/32bit.
Fixed literal string bug in 32bit mode.
Cleaned up manual and moved history/roadmap to history.txt
2.39 I
mproved string literal handling and fixed a bug where it wouldn�t work in vararg parameters.
Added DEFINE/UNDEF built-in commands.
Optimised SWITCH generated code, moved jump tables to data sections to avoid affecting code sections/code caching and line number to offset references.
Added OPTION SWITCHSIZE
Changed architecture default from AVX to SSE for improved default compatibility.
2.38
Fixed more listing issues with binary zeroes.
Improved UTF bom check performance by moving to ProcessFile (Nidud)
Fixed an encoding issue with LEA and RIP.
Fixed IFNDEF macro generation bug.
Fixed SYSCALL, FASTCALL64 and VECTORCALL parameter order and type checking bugs.
Added new instructions: ADOX, VAESDEC, ADCX, CLAC, RDPID, CLFLUSHOPT
Fixed an index register encoding bug and improved checking for valid forms of vscatter and vgather.
2.37
Fixed listing bug causing a binary zero in output text.
Added support for implicit sizing and DS segment overrides for 32bit code generation.
Added support for new 64bit absolute immediate addressing modes.
2.36
Added automatic alignment check for all SIMD instructions which are not scalar.
Improved simd type coercion by testing variables (global/local) on size rather than type. This simplifies code and reduces the need to use type ptr when working with DWORD, BYTE or other data types.
Fixed a bug with literal string support handling \n escape.
Improved handling of PTR and VARARG for SystemV calls.
2.35
Fixed some register combination warnings for VCMPSD, VCMPEQSD and VCMPSS.
Added RP4/RP8 macros and case-sensitive conversion to macro library.
Added support for floating point comparison expression.
Add string literal support back into invoke.
2.34
Added �Sp command line switch to allow user specified segment alignment.
Added further Intel MPX extension support, including BND prefix support.
Added support to define return types on PROC/PROTO which enables the use of the new UINVOKE macro library function.
2.33
Fixed a number of regression issues, including several VEX encoded instructions which were not correct.
Fixed ebx.STRUCT style addressing.
Fixed SYSV support to allow ADDR in VARARGS.
Fixed a potential crash when running multiple input files.
2.32
Added initial UTF8 BOM Check
Rolled-back literal string support in favour of using existing CSTR/WSTR macros to ensure no legacy invoke calls are broken. Literal string support will be moved to a new invocation syntax.
2.31
Fixed 32bit MS FASTCALL issue.
Fixed encoding bug with VMOVQ.
Fixed VMOVSS/VMOVSD allowing 2 register form, when 3 registers are required for all-register mode and added error message for it.

Optimised and improved FASTCALL handlers and completely redeveloped SYSTEMV calling convention implementation.
Fixed a potential memory corruption bug in the symbol table.
Added support for Intel MPX extensions, bnd0-3 registers and new instructions.

Improved Linux 64bit package and compilation to use clang as per OSX so both builds are compatible.
2.29
Finalized Delphi (Borland Register calling convention) and updated language type specifier to BORLAND.
Fixed some register overwrite issues with SystemV invoke.

Fixed a potential general failure crash with some evex encodings when no base-register present.
Fixed 32bit crash caused by Macro Library modifying read only string data.
2.28

OPTION PROC can also set prologue/epilogue simultaneously with:
OPTION PROC:PrologueMacro,EpilogueMacro
Change macro library OO functions names to use _ instead of $.
Added DELPHI language type for Borland 32bit fast-calling convention.
(experimental, pending further updates)
Fix SHR for macro expression evaluation (Fix supplied by Nidud).
Fix VARARG Register overwritten warning.

2.27
Fixed the use of ADDR in invoke for SYSTEM V calls.
Disable generation of listing while processing built-in macro library.
Rename OO INTERFACE function in built-in macro library to OINTERFACE and ENDINTEFACE to ENDOINTERFACE to prevent conflicts with SDK headers.

Added support for allocating wide strings in data with dw.
Automatic integer to float promotion for data declarations and struct members.
Added new union initialisation syntax.
Added built-in macro library that precompiles and adjusts to suit currently selected architecture setting (SSE/AVX).

Added support to INVOKE allowing XMM register parameters for FLOAT type arguments (real4 and real8).
Fixed stack and local align to 16 issues.
Added OPTION ARCH:<SSE|AVX> and command line
switches �archSSE �archAVX to change code-generation to favour SSE or AVX instructions (this is particularly relevant to invoke and prologue/epilogue generation).
2.20
Fixed opcode byte 83 to be 80 when assembler needs to assume BYTE type.
Cleaned up linnum memory allocation from switch additions.
Fixed option win64:6

- Maintains all UASM 64bit HLL features like PROC, FRAME, INVOKE, .FOR, .SWITCH, VECTORCALL etc.
- See new example flat.asm
Fixup ORG directive generation which incorrectly pads the code buffer with 0�s instead of simply applying the address change
Add support for .labelName style labels (like nasm/fasm support)
2.16
Complete re-working of AVX2 and AVX512 code generation to ensure that encodings are separated.
Complete implementation of all missing AVX2 and AVX512 instructions.
Added extensive checking to prevent misuse of register and memory operands with AVX, AVX2 and AVX512 instructions especially where mask and decorator flags are required.
All AVX512 code now tested against Intel SDE emulation libraries.
2.15 r2
