Fabrice,
 
Good news! The C67 port seems to compile, run, and generate correct C67
code.
 
Below is a diff of the directory I was testing in.
 
The changes to tcccoff.c I belive are all straighforward bugs and should be
incorporated.
 
The rest are make/header/compiler issues which you may have a better way to
address. There are a couple of linux headers that don't seem to be required
by tcc but give problems for MinGW (or MS VC++). Similarly there are
references to "long long". Also a few minor compiler issues.
 
I couldn't find a good way to debug the MinGW generated exe. Is there one?
The only thing I could find is a command line gdb. So I resorted back to MS
VC++ to compile and debug. It seemed too easy. I just made an empty
project, inserted tcc.c and it compiled an ran!
 
 
 
Here is the process I went through on my Windows Machine (possibly useful to
someone as ignorant of Linux as me):
 
1 - Install Cygwin (including development tools)
2 - Install MinGW
3 - from Cygwin prompt checkout tcc with:
cvs -z3 -d:ext:address@hidden:/cvsroot/tinycc co tinycc
4 - I resorted to editing the configure script to force mingw32="yes"
5 - from Cygwin prompt: configure
6 - from windows cmd prompt: cd to where CVS put the files (cd
C:\cygwin\home\TK\tinycc)
6 - from windows cmd prompt: put Mingw\bin in your path=$path$;c:\mingw\bin
7 - from windows cmd prompt: mingw32-make.exe C67-tcc.exe
8 - from windows cmd prompt: C67-tcc.exe -g -nostdlib test.c -o test.out
 
 
Let me know your thoughts.
 
Thanks
 
TK

I commited an initial support for win32 in the configure script and in
the Makefile. You must use the mingw32 tools to compile TCC. Feel free
to send any improvement.
 
Fabrice.

It's ok. BTW, Fabrice, if you're intrested, I can offer you macro which
defines intxx_t types for compilers who don't defines it.
 
< if ((n & 0xffffffff00000000LL) != 0) {
---
> if ((n & ((int64_t)0xffffffff00000000)) != 0) {
 
This code is wrong. You try to cast into int64_t in order to get some 64
bits value, this means you consider you have a 32 bits one. If the constant
is 32 bits, this means you lost half the bits and the cast won't recover
them.
 
The good definition is: if ((n & INT64_C(0xffffffff00000000)) != 0) {
 
The definitions I proposed defines INTxx_C too for old compilers which
use their own syntax.
 
Best regards,

The README file said
"Requires Windows 95, NT 4.0, or better."
So... I installed it on Linux!

Hi,
 
Unless more people want MS VC++ support, I am relunctant to merge VC++
specific patches as I cannot test them. Why do you use _open() instead
of open() ? Would the O_BINARY flag improve things ?
 
Now that there is an example to output another format than ELF, maybe
someone will add PECOFF support !
 
Fabrice.
 
PS: Try to send 'diff -u' patches, they are easier to read...
