This is a modified version of musl libc 1.12 which is able to be
compiled with TinyCC on x86_64 machines.
Although TinyCC is quite complete as a tiny C compiler,some features are
still missing,including:
- _Complex types
All related to _Complex are removed.
- Full GNU-style inline assembly support.
The original versions of __syscall4(),__syscall5() and __syscall6()
don't work.They are replaced by assembly implemention in
/src/internal/x86_64/syscall.S
- math library is removed momently.
Because some missing floating-point features of TinyCC.I am working
on completing.
- @PLT dynamic linking function calls are removed.
TinyCC does not have the feature.Dynamic linking library(.so)
is expected not to work.
Some features had been removed momently but now they are usable,including:
- fenv library(maybe applying a patch to TinyCC is needed)
To compile,simply run
export CC=tcc # Set the compiler
export RANLIB='tcc -r' # Using tcc builtin librarian
export AR='tcc -ar' # See above
./configure --target=x86_64 # The script cannot detect the
# platform with tcc because of
# missing option "-dumpmachine"
make # I finish my compiling in 10s with
two threads on i7-720QM @ 1.60GHz
All modified and addtional files are under MIT License as well.
Some changes are made to my TinyCC (This means I may have a different
version from yours,so if you fail to compile,try to apply the patches
listed in /tcc-patch/,including:
- empty_archive.patch
Enables TinyCC to generate empty ar archive
- mxcsr.patch
Adds the support of ldmxcsr and stmxcsr
