ok ,

But the fc-- must tell us that instead of crashing..!!

bazizmix,

one of the best things of fc-- is that , using a function of dll without declaration , just import the dll library then go.

but , declaring the call convention of function tells the compiler how to balance the stake , so that you do not need this



any way ,hope fc-- grows , relay it's a good project.

The next version of FlatC--:
FlatC-- Version 0.88 XAC(C)2017.
Based on ideas Peter Cellik & Tomasz Grysztar.
Usage: fc--.exe [/list] [/debug] <Source file>
/list << generate asm listing
/debug << generate debug info for x64dbg
New:
1) Generation of 32/64-bit programs (keywords - win32/win64). By defaul - win32.
List of supported instructions in the file Mnemonics.txt.
2) Fastcall method for dll functions are implemented in 64-bit mode.
Also fastcall implemented for windows callback functions:
WindowProc(qword hwnd:rcx,wmsg:rdx,wparam:r8,lparam:r9)
3) Conditional compiling realized: #ifdef, #ifndef, #else and #endif.

Thanks for feedbacks

Next version:

Now FlatC-- has 32-bit and 64-bit executable files (fc--32.exe and fc--64.exe).
The mandatory command-line parameter is added
to generate 32-bit and 64-bit executables:
/32 for 32-bit. The constant WIN32 = TRUE, WIN64 = FALSE
/64 for 64-bit. The constant WIN32 = FALSE, WIN64 = TRUE
Commands win32 and win64 was removed.
Constants RAX, RBX, RCX, RDX, RDI, RSI, RBP, RSP and INTSIZE are introduced.
When specifying the /32 command-line parameter, they take the values:
eax, ebx, ecx, edx, edi, esi, ebp, esp and INTSIZE=4.
When specifying the /64 command-line parameter, they take the values:
rax, rbx, rcx, rdx, rdi, rsi, rbp, rsp and INTSIZE=8.
Thus, the expression with /32 parameter will be compiled as
,
and with the /64 parameter, as
.
Was made some optimization in generated code.

I'm interested in your opinion.

Soon a new version will appear that is fairly close to the C standard.
