Rich Felker	9ec4283b28	add support for TLS variant I, presently needed for arm and mips despite documentation that makes it sound a lot different, the only ABI-constraint difference between TLS variants II and I seems to be that variant II stores the initial TLS segment immediately below the thread pointer (i.e. the thread pointer points to the end of it) and variant I stores the initial TLS segment above the thread pointer, requiring the thread descriptor to be stored below. the actual value stored in the thread pointer register also tends to have per-arch random offsets applied to it for silly micro-optimization purposes. with these changes applied, TLS should be basically working on all supported archs except microblaze. I'm still working on getting the necessary information and a working toolchain that can build TLS binaries for microblaze, but in theory, static-linked programs with TLS and dynamic-linked programs where only the main executable uses TLS should already work on microblaze. alignment constraints have not yet been heavily tested, so it's possible that this code does not always align TLS segments correctly on archs that need TLS variant I.	14 years ago
Rich Felker	9c74856af7	dynamic-linked TLS support for everything but dlopen'd libs currently, only i386 is tested. x86_64 and arm should probably work. the necessary relocation types for mips and microblaze have not been added because I don't understand how they're supposed to work, and I'm not even sure if it's defined yet on microblaze. I may be able to reverse engineer the requirements out of gcc/binutils output.	14 years ago

Rich Felker	32de61e81a	fix some symbol resolution issues in dynamic linker 1. search was wrongly beginning with lib itself rather than dso head 2. inconsistent resolution of function pointers for functions in plt	15 years ago
Rich Felker	568b8075a4	proper path searching for dynamic linker first, use $LD_LIBRARY_PATH unless suid. if that fails, read path from /etc/ld-musl-$ARCH.path and fallback to a builtin default.	15 years ago
Rich Felker	51e2d83102	experimental dynamic linker! some notes: - library search path is hard coded - x86_64 code is untested and may not work - dlopen/dlsym is not yet implemented - relocations in read-only memory won't work	15 years ago
