UASM 2.51.2

* regcall implementation for 64bits win/linux/mach, it follows the same principe off the base OS system convention. Now fixed the segfault using language convention with proto for linux/mac 64bits.
* regcall atempt implementation for 32bits win/linux. Now fixed the segfault using language convention with proto for all 32bits system's
* thiscal for 32 bits win.
* syscall linux kernel parameters, only the 6 arguments are implemented, the UASM user must be aware of the return address and system call number etc...
* Fix VPTESTMW VPTESTMM VPTESTNMW VPTESTMB.
* Fix dbgcv.c (_getcwd) to portable code.
* Fix dbgcv.c (_pgmptr) to portable code.
* Add getexec.c with code for get current executable directory path, heart of portable code for getExecutablePath().
* Striped macrolib to *.inc files, for better contribution without the need to recompile UASM, now executable low as 700kb win / 800kb linux.
* and added new macro lib utilities.
* Added Setup Project for windows, using the free version of Advanced Installer.
* Added ubuntu/debian package manager project.
* Small fix for elf64_relocations now using R_X86_64_GOTPCREL64 = 28, /* G + GOT - P + A */
* added option frame:none for linux/mac 64bits only and for manual procedure optimization.
* all code now is aligned for 64bits builds to 16 bytes, but the packed 1 byte code stays the same.
* Pull request Terraspace#138 define alloca only if not defined and not the proposed pointer casting changes it will break uasm.
* Pull request Terraspace#141 strlen() moved from the body for cycle.
* Pull request Terraspace#137 Allow overriding the SWITCHCHAR option by passing -DSWITCHCHAR=0/1 when building.
* Fix by @nidud dbgcv.c corrupted debug info.
* Updated debian package manager distribution for multiple build release and debug files.

Check setup installer for.

Windows Setup, add the necessary path environment variables, and MSBuild BuildCustomizations for VS2019.

Windows setup also installs uasmd debug version and also has 32 bits binaries.

windows:
Win Setup
or
Win binaries files

linux:
Linux 64 bits binaries

Linux installs to /usr/bin/uasm and inc files to /usr/include/uasm

ubuntu apt package manager:

tested and shlx eax, eax, edx works in windows and linux assembling

msi file do checks for current environments PATHS, yep slow with earlier version of windows

zip file also added above. Win binaries files

tested and shlx eax, eax, edx works in windows and linux assembling

Sorry, misunderstanding: not my code crashes, but yours: UAsm itself crashes because my very, very old Core i5 doesn't understand shlx

No problem, version v2.51 of Feb 27 works perfectly on my stone age hardware

Is this branch v2.51.2 in Git too ?

Windows 7:
UASM Assembler has stopped working

[KradMoonRa]

Sorry guys, not everyone has AVX2, my mistake 

Rebuild defaults no AVX or higher.

windows:
Win Setup Uninstall and Install again.
or
Win binaries files Copy hover.

Thanks, we will test it

Some glitches to resolve... attached example works fine with MASM 6.14 and others.

Hi John,

I managed to identify a bug that was not present in the previous version 2.50. The bug occurs on large projects when there are too many include files. An error and an unexpected stop always occur in a different place. I have attached a test case, I can consistently repeat this error.

Hi KradMoonRa,

could You please add a version for AVX2 to the releases folder? It can be separately marked as AVX2. What options are required in Visual Studio for AVX2, to compile with optimization?
