1 | Tiny C Compiler - C Scripting Everywhere - The Smallest ANSI C compiler

4 | Features:
|
---|
5 | --------
|
---|
6 |
|
---|
7 | - SMALL! You can compile and execute C code everywhere, for example on
|
---|
8 | rescue disks.
|
---|
9 |
|
---|
10 | - FAST! tcc generates optimized x86 code. No byte code
|
---|
11 | overhead. Compile, assemble and link about 7 times faster than 'gcc
|
---|
12 | -O0'.
|
---|
13 |
|
---|
14 | - UNLIMITED! Any C dynamic library can be used directly. TCC is
|
---|
15 | heading torward full ISOC99 compliance. TCC can of course compile
|
---|
16 | itself.
|
---|
17 |
|
---|
18 | - SAFE! tcc includes an optional memory and bound checker. Bound
|
---|
19 | checked code can be mixed freely with standard code.
|
---|
20 |
|
---|
21 | - Compile and execute C source directly. No linking or assembly
|
---|
22 | necessary. Full C preprocessor included.
|
---|
23 |
|
---|
24 | - C script supported : just add '#!/usr/local/bin/tcc -run' at the first
|
---|
25 | line of your C source, and execute it directly from the command
|
---|
26 | line.
|

28 | Documentation:
|
---|
29 | -------------
|
---|
30 |
|
---|
31 | 1) Installation on a i386/x86_64/arm Linux/OSX/FreeBSD host
|
---|
32 |
|
---|
33 | ./configure
|
---|
34 | make
|
---|
35 | make test
|
---|
36 | make install
|
---|
37 |
|
---|
38 | Notes: For OSX and FreeBSD, gmake should be used instead of make.
|
---|
39 | For Windows read tcc-win32.txt.
|
---|
40 |
|
---|
41 | makeinfo must be installed to compile the doc. By default, tcc is
|
---|
42 | installed in /usr/local/bin. ./configure --help shows configuration
|
---|
43 | options.

46 | 2) Introduction
|
---|
47 |
|
---|
48 | We assume here that you know ANSI C. Look at the example ex1.c to know
|
---|
49 | what the programs look like.
|
---|
50 |
|
---|
51 | The include file <tcclib.h> can be used if you want a small basic libc
|
---|
52 | include support (especially useful for floppy disks). Of course, you
|
---|
53 | can also use standard headers, although they are slower to compile.
|
---|
54 |
|
---|
55 | You can begin your C script with '#!/usr/local/bin/tcc -run' on the first
|
---|
56 | line and set its execute bits (chmod a+x your_script). Then, you can
|
---|
57 | launch the C code as a shell or perl script :-) The command line
|
---|
58 | arguments are put in 'argc' and 'argv' of the main functions, as in
|
---|
59 | ANSI C.
|
---|
60 |
|
---|
61 | 3) Examples
|
---|
62 |
|
---|
63 | ex1.c: simplest example (hello world). Can also be launched directly
|
---|
64 | as a script: './ex1.c'.
|
---|
65 |
|
---|
66 | ex2.c: more complicated example: find a number with the four
|
---|
67 | operations given a list of numbers (benchmark).
|
---|
68 |
|
---|
69 | ex3.c: compute fibonacci numbers (benchmark).
|
---|
70 |
|
---|
71 | ex4.c: more complicated: X11 program. Very complicated test in fact
|
---|
72 | because standard headers are being used ! As for ex1.c, can also be launched
|
---|
73 | directly as a script: './ex4.c'.
|
---|
74 |
|
---|
75 | ex5.c: 'hello world' with standard glibc headers.
|
---|
76 |
|
---|
77 | tcc.c: TCC can of course compile itself. Used to check the code
|
---|
78 | generator.
|
---|
79 |
|
---|
80 | tcctest.c: auto test for TCC which tests many subtle possible bugs. Used
|
---|
81 | when doing 'make test'.
|
---|
82 |
|
---|
