README

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 
	./configure --target=x86_64 CC='tcc' AR='tcc -ar' RANLIB='echo' \
		    LIBCC='/usr/local/lib/tcc/libtcc1.a'
	make				# I finish my compiling in 10s with
					  two threads on i7-720QM @ 1.60GHz
TinyCC's runtime environment library libtcc1.a needs specifying manually
now.The path of argument LIBCC may need adjusting for your machine.

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
