2011-02-18support the ugly and deprecated ucontext and sigcontext header stuff...Rich Felker-0/+32
only the structures, not the functions from ucontext.h, are supported at this point. the main goal of this commit is to make modern gcc with dwarf2 unwinding build without errors. honestly, it probably doesn't matter how we define these as long as they have members with the right names to prevent errors while compiling libgcc. the only time they will be used is for propagating exceptions across signal-handler boundaries, which invokes undefined behavior anyway. but as-is, they're probably correct and may be useful to various low-level applications dealing with virtualization, jit code generation, and so on...
2011-02-17reorganize pthread data structures and move the definitions to alltypes.hRich Felker-0/+15
this allows sys/types.h to provide the pthread types, as required by POSIX. this design also facilitates forcing ABI-compatible sizes in the arch-specific alltypes.h, while eliminating the need for developers changing the internals of the pthread types to poke around with arch-specific headers they may not be able to test.

2011-02-15remove standalone syscall cruftRich Felker-11/+1
this was originally written for an early draft of the library where non-standard functions would reside in a static library separate from the shared libc.so, which would implement a pure standard. the idea was not to depend on an implementation-dependent __syscall_ret function in the main libc. but it turned out to be better to put everything in a single library for both static and dynamic linking uses, and thus the (incomplete) remnants of this feature were just enlarging the source and binary.
