Emne: Re: [Tinycc-devel] Duplicate double

Hi,

The simple answer, with MSYS2, to build tcc win64:
- Start MSYS2 shortcut "mingw64", ensure you have mingw gcc x86-64 installed.
- Clone tinycc and cd to the root source dir.
- Run `mkdir build64 && cd build64 && ../configure --cpu=x86-64 
--prefix=$(pwd)/dist && make && make install`
- Now the `./dist/` dir will have a working portable tcc win64 package/files.

To build tcc win32, use the same steps but instead start the "mingw32" MSYS2
shortcut, ensure you have mingw gcc i686 installed, and use --cpu=i386 (and
optionally different build/install dirs).

The resulting tcc will use relative lib/include files.

However, like Christian, I also use a reproducible build script which I wrote.
It can use any compiler (gcc/clang/tcc/etc) on most systems (cygwin, linux,
macOS, freeBSD, etc) to create a reproducible windows tcc compilers with
identical binaries regardless of the system on which it was created.

Like Christian's script, it first builds (possibly) cross compilers tcc for
windows (which target win32 and win64), then uses them to build 32 and 64 tcc
as well as 2 cross compilers (win64 tcc which targets win32, and win32 tcc
which targets win64). Overall 4 distributions.

The dirs I put at the 7z file are the plain 32/64 builds of tcc (not cross).

To use it:
- Get this file: 
https://github.com/avih/tinycc/blob/mob-win32-repro/win32/build-tcc-reproducible.sh
- Place it at the /win32/ dir and cd into that dir.
- Run `rm -rf ./reprobuild; ./build-tcc-reproducible.sh`
- Too see more options, run it with `-h`

Cheers,
Avi

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.

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

Remove C:\msys64 if present

Go to https://www.msys2.org/
Click msys2-x86_64-20190524.exe
Install msys2 using defaults

In MSYS2 shell:
> pacman -Syu
As instructed, kill and restart MSYS2 shell
> pacman -Syu
> pacman -S gcc git make texinfo
> git clone git://repo.or.cz/tinycc.git
> cd tinycc
> ./configure --prefix=/usr --bindir=/usr/bin
> make
> make install
> cd
> tcc -v
tcc version 0.9.27 (x86_64 Windows)
> mkdir experiment
> cd experiment
> cat>test.c
#include 
void f(double x,double y,double z){printf("f(%4.1f,%4.1f,%4.1f)\n",x,y,z);}
int main(int argc,char **argv){double u=0.0;f(u*1.0,7.0,8.0);return 0;}
> tcc -o test test.c
> ./test
f( 0.0, 7.0, 8.0)

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

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
