Hello Klaus,
I don't know how Avi builds tcc on Windows but, on my side, I have made this
companion repository that works well with Cygwin:
https://sourceforge.net/projects/wintcc/
Basically, get the cygwin/Makefile you have to drop in tcc/win32, and just run
"make" (files in includes are already integrated in tcc and you don't need
them)It builds a native tcc 32/64 compiler built with tcc bootstrapped with gcc
(i.e. a reproductible build).A Makefile named "tarball" produces a standalone
.zip you can use on any Windows machine.tcc compiled binary does not need
cygwin runtime to be present.
I don't understand quite well why Grischka refused to add it on official tcc
distrib.
C.

Hi again Avi,
Can I persuade you to tell how you built
https://0x0.st/zOsg.7z ?
In particular, how you made the lib and includes relative to the location of
'tcc.exe' for tcc32 and tcc64.
Googling around seems to suggest that one should use the right host (MinGW?
Cygwin?) and use the right ./configure options.
Cheers,
Klaus

Hi Avi,
Great! Thanks!
https://0x0.st/zOsg.7z worked.
Just to test, I made a fresh msys2 install, cloned git://repo.or.cz/tinycc.git
and compiled. That also works.
For completeness, I have included the steps. The only surprise was that when
using .configure --prefix=/usr I had to add --bindir=/usr/bin since otherwise
tcc ends up in /usr/tcc.exe
Cheers,
Klaus

Emne: Re: [Tinycc-devel] Duplicate double
You're right, and I can confirm that the win64 version downloaded the
same as you exhibits the same issue, and the issue also exists if
I build 0.27 for win64 myself (git d348a9a).
However, it was apparently fixed shortly after tcc 0.27 was released,
at the following commit:
commit 8f6fcb709ae7b2379866c292ce478ab95dc75b48
Author: grischka <grischka>
Date: Thu May 31 23:51:51 2018 +0200
misc fixes
misc fixes including:
- tcc.c: fix "tcc -vv" for libtcc1.a on win32/PE
- tccelf.c: fix a crash when GOT has no relocs (witn -nostdlib)
- tccelf.c: fix stab linkage for zero n_strx
- tccgen.c: fix stdcall decoration for array parameters
int __stdcall func(char buf[10]) is _func@4 (was _func@12)
- tccgen.c: fix static variables with nocode/nodata_wanted
see tests2/96_nodata_wanted.c
- tccrun.c: align sections using sh_addralign (for reliable function_alignment)
- tests2/Makefile sort 100 after 99
- win32/include/sys/stat.h fix _stat and _wstat
- x86_64-gen.c: win64/gfunc_call: fix a bug with xmmN register args
previously overwrote valid other xmmN registers eventually
Not sure which of the fixes did it, but I'd guess it's at x86_64-gen.c .
If you want, I've built tcc for win32 and win64 from the latest git
version (mob, 9e429db), and uploaded it here: https://0x0.st/zOsg.7z
Cheers,
Avi

Hi tinycc-devel,
Under MSYS2/MinGW I have a problem with tcc.
I define this functions:
void f(double x,double y,double z){printf("f(%4.1f,%4.1f,%4.1f)\n",x,y,z);}
As an example, f(1,2,3) prints f( 1.0, 2.0, 3.0).
Then I call f from main in a slightly confusing way:
int main(int argc,char **argv){double u=0.0;f(u*1.0,7.0,8.0);return 0;}
I would expect to get f( 0.0, 7.0, 8.0) but I do get f( 7.0, 7.0, 8.0).
The first argument of f becomes a duplicate of the second argument of f.
If I remove "*1.0" then everything works as expected.
Is this a known bug?
By the way, if I make the same program using integers, then there is no problem.
I have included a reproduction scenario below.
Cheers,
Klaus
