musl - The musl libc tree (WIP / dev branches)

Age	Commit message (Collapse)	Author	Files	Lines
2012-10-18	use $CC rather than "$CC" in configure script	Rich Felker	1	-4/+4
	this is necessary to allow $CC with arguments in it
2012-10-03	tell the assembler to mark all files as not requiring executable stack	Rich Felker	1	-0/+7
	for some reason this option is undocumented. not sure when it was added, so I'm using a configure test. gcc was already setting the mark correctly for C files, but assembler source files would need ugly .note boilerplate in every single file to achieve this without the option to the assembler. blame whoever thought it would be a good idea to make the stack executable by default rather than doing it the other way around...
2012-09-29	microblaze port	Rich Felker	1	-0/+1
	based on initial work by rdp, with heavy modifications. some features including threads are untested because qemu app-level emulation seems to be broken and I do not have a proper system image for testing.
2012-09-10	add LIBCC (compiler runtime) logic and override to configure	Rich Felker	1	-0/+7
	this should both fix the issue with ARM needing -lgcc_eh (although that's really a bug in the libgcc build process that's causing considerable bloat, which should be fixed) and make it easier to build musl using clang/llvm in place of gcc. unfortunately I don't know a good way to detect and support pcc's -lpcc since it's not in pcc's default library search path...
2012-08-29	get rid of eh_frame bloat	Rich Felker	1	-3/+12
	if needed for debugging, it will be output in the .debug_frame section instead, where it is not part of the loaded program and where the strip command is free to strip it.
2012-08-25	add gnu hash support in the dynamic linker	Rich Felker	1	-1/+1
	based on the patches contributed by boris brezillon.
2012-08-14	support configuring cross compiling with CROSS_COMPILE prefix variable	Rich Felker	1	-3/+6

2012-08-05	make configure accept mipsel	Rich Felker	1	-1/+1

2012-08-05	remove configure check disabling shared libraries on mips	Rich Felker	1	-4/+0

2012-07-12	disable dynamic linking on mips for now (broken)	Rich Felker	1	-0/+5

2012-07-11	initial version of mips (o32) port, based on work by Richard Pennington (rdp)	Rich Felker	1	-0/+1
	basically, this version of the code was obtained by starting with rdp's work from his ellcc source tree, adapting it to musl's build system and coding style, auditing the bits headers for discrepencies with kernel definitions or glibc/LSB ABI or large file issues, fixing up incompatibility with the old binutils from aboriginal linux, and adding some new special cases to deal with the oddities of sigaction and pipe syscall interfaces on mips. at present, minimal test programs work, but some interfaces are broken or missing. threaded programs probably will not link.
2012-07-03	configure: only use -ffloat-store on i386	Rich Felker	1	-1/+1
	this option is expensive and only used on old gcc's that lack -fexcess-precision=standed, but it's not needed on non-i386 archs where floating point does not have excess precision anyway. if musl ever supports m68k, i think it will need to be special-cased too. i'm not aware of any other archs with excess precision.
2012-06-07	check for ld support of -Bsymbolic-functions; disable shared if not avail	Rich Felker	1	-0/+7
	this issue affects the last gpl2 version of binutils, which some people are still using out of aversion to gpl3. musl requires -Bsymbolic-functions because it's the only way to make a libc.so that's able to operate prior to dynamic linking but that still behaves correctly with respect to global vars that may be moved to the main program via copy relocations.
2012-06-07	use -nostdlib in linker tests to avoid possible missing crt/lib issues	Rich Felker	1	-1/+1

2012-06-07	avoid linking main program in linker tests	Rich Felker	1	-2/+2
	it's possible that the user has provided a compiler that does not have any libc to link to, so linking a main program is a bad idea. instead, generate an empty shared library with no dependencies.
2012-06-06	make configure try to disable stack protector	Rich Felker	1	-0/+2
	in theory we could support stack protector in the libc itself, and users wanting to experiment with such usage could add -fstack-protector to CFLAGS intentionally. but to avoid breakage in the default case, override broken distro-patched gcc that forces stack protector on.
2012-06-06	add configure check for gnu linker hash style setting	Rich Felker	1	-1/+20
	some broken distro-provided toolchains have modified gcc to produce only "gnu hash" dynamic hash table by default. as this is unsupported by musl, that results in a non-working libc.so. we detect and switch this on in configure rather than hard-coding it in the Makefile because it's not supported by old binutils versions, but that might not even be relevant since old binutils versions already fail from -Bsymbolic-functions being missing. at some point I may review whether this should just go in the Makefile...
2012-06-03	fix configure build/host/target terminology usage	Rich Felker	1	-13/+14

2012-05-14	yet another try to get the check for gcc right...	Rich Felker	1	-1/+1

2012-05-14	fix error in last configure change (lack of escaping)	Rich Felker	1	-1/+1

2012-05-13	correct the check for gcc (previous version failed for cross compilers)	Rich Felker	1	-1/+1

2012-05-05	add -frounding-math to build	Rich Felker	1	-0/+1

2012-05-04	initial commit of configure script	Rich Felker	1	-0/+275
	this script is not based on autoconf; however it attempts to follow the same interface contracts for ease of integration with build systems. it is also not necessary to use musl. manually written config.mak files are still supported, as is building without any config.mak at all as long as you are happy with the default options and you supply at least ARCH on the command line to make.
