- Use runtime function for conversion
- Also initialize fp with tcc -run on windows
This fixes a bug where
double x = 1.0;
double y = 1.0000000000000001;
double z = x < y ? 0 : sqrt (x*x - y*y);
caused a bad sqrt because rounding precision for the x < y comparison
was different to the one used within the sqrt function.
This also fixes a bug where
printf("%d, %d", (int)pow(10, 2), (int)pow(10, 2));
would print
100, 99

TinyCC
|
|
======
|
|
|
|
This file contains specific information for usage of TinyCC
|
|
under MS-Windows. See tcc-doc.html to have all the features.
|
|
|
|
|
|
Installation from the binary ZIP package:
|
|
-----------------------------------------
|
|
Unzip the package to a directory of your choice.
|
|
|
|
|
|
Set the system PATH:
|
|
--------------------
|
|
To be able to invoke the compiler from everywhere on your computer by
|
|
just typing "tcc", please add the directory containing tcc.exe to your
|
|
system PATH.
|
|
|
|
|
|
Include and library search paths
|
|
--------------------------------
|
|
On windows, the standard "include" and "lib" directories are searched
|
|
relatively from the location of the executables (tcc.exe, libtcc.dll).
|
|
|
|
|
|
Examples:
|
|
---------
|
|
Open a console window (DOS box) and 'cd' to the examples directory.
|
|
|
|
For the 'Fibonacci' example type:
|
|
|
|
tcc fib.c
|
|
|
|
For the 'Hello Windows' GUI example type:
|
|
|
|
tcc hello_win.c
|
|
|
|
For the 'Hello DLL' example type
|
|
|
|
tcc -shared dll.c
|
|
tiny_impdef dll.dll (optional)
|
|
tcc hello_dll.c dll.def
|
|
|
|
|
|
Using libtcc as JIT compiler in your program
|
|
--------------------------------------------
|
|
Check out the 'libtcc_test' example:
|
|
|
|
- Running it from source:
|
|
tcc -I libtcc libtcc/libtcc.def -run examples/libtcc_test.c
|
|
|
|
- Compiling with TCC:
|
|
tcc examples/libtcc_test.c -I libtcc libtcc/libtcc.def
|
|
|
|
- Compiling with MinGW:
|
|
gcc examples/libtcc_test.c -I libtcc libtcc.dll
|
|
|
|
- Compiling with MSVC:
|
|
lib /def:libtcc\libtcc.def /out:libtcc.lib
|
|
cl /MD examples/libtcc_test.c -I libtcc libtcc.lib
|
|
|
|
|
|
Import Definition Files:
|
|
------------------------
|
|
To link with Windows system DLLs, TCC uses import definition
|
|
files (.def) instead of libraries.
|
|
|
|
The included 'tiny_impdef' program may be used to make additional
|
|
.def files for any DLL. For example:
|
|
|
|
tiny_impdef.exe opengl32.dll
|
|
|
|
Put opengl32.def into the tcc/lib directory. Specify -lopengl32 at
|
|
the TCC commandline to link a program that uses opengl32.dll.
|
|
|
|
|
|
Header Files:
|
|
-------------
|
|
The system header files (except _mingw.h) are from the MinGW
|
|
distribution:
|
|
|
|
http://www.mingw.org/
|
|
|
|
From the windows headers, only a minimal set is included. If you need
|
|
more, get MinGW's "w32api" package. Extract the files from "include"
|
|
into your "tcc/include/winapi" directory.
|
|
|
|
|
|
Resource Files:
|
|
---------------
|
|
TCC can link windows resources in coff format as generated by MinGW's
|
|
windres.exe. For example:
|
|
|
|
windres -O coff app.rc -o appres.o
|
|
tcc app.c appres.o -o app.exe
|
|
|
|
|
|
Tiny Libmaker:
|
|
--------------
|
|
The included tiny_libmaker tool by Timovj Lahde can be used as
|
|
'ar' replacement to make a library from several object files:
|
|
|
|
tiny_libmaker [rcs] library objectfiles ...
|
|
|
|
|
|
Compilation from source:
|
|
------------------------
|
|
* You can use the MinGW and MSYS tools available at
|
|
|
|
http://www.mingw.org
|
|
|
|
Untar the TCC archive and type in the MSYS shell:
|
|
|
|
./configure [--prefix installpath]
|
|
make
|
|
make install
|
|
|
|
The default install location is c:\Program Files\tcc
|
|
|
|
* Alternatively you can compile TCC with just GCC from MinGW using
|
|
|
|
build-tcc.bat (from the win32 directory)
|
|
|
|
To install, copy the entire contents of the win32 directory to
|
|
where you want.
|
|
|
|
|
|
Limitations:
|
|
------------
|
|
- On the object file level, currently TCC supports only the ELF format,
|
|
not COFF as used by MinGW and MSVC. It is not possible to exchange
|
|
object files or libraries between TCC and these compilers. However
|
|
libraries for TCC from objects by TCC can be made using tiny_libmaker
|
|
or MinGW's ar.
|
|
|
|
- No leading underscore is generated in the ELF symbols.
|
|
|
|
- Bounds checking (option -b) is not supported on 64-bit OS.
|
|
|

WinAPI Help and 3rd-party tools:
|
|
--------------------------------
|
|
The Windows API documentation (Win95) in a single .hlp file is
|
|
available on the lcc-win32 site as "win32hlp.exe" or from other
|
|
locations as "win32hlp_big.zip".
|
|
|
|
A nice RAD tool to create windows resources (dialog boxes etc.) is
|
|
"ResEd", available at the RadASM website.
