Date: Sat, 25 Aug 2012 21:42:25 -0400 From: Gregor Richards <gr@...due.edu> To: musl@...ts.openwall.com Subject: C11 low-hanging fruit Attached is a diff that adds the trivially-simple bits of C11. That is, those that require changes to the standard headers, but very little in the way of implementation. Included are: * stdalign.h , including backwards compatibility for GCC. * aligned_alloc * fopen(..., "...x") * conditional removal of gets Excluded are: * threads.h (waiting to see glibc's ABI) * stdatomic.h (complicated, probably has ABI implications too, not even fully supported by GCC yet) * uchar.h (this is MOSTLY trivial since musl's wchar is Unicode anyway, but char32_t makes it a bit more than some weak aliases) * at_quick_exit, quick_exit (I suspect that our benevolent dictator will have a lot to say in exactly what makes an exit "quick" or not, so I'm not touching this) I used __STDC_VERSION__ in the headers to control exposure of aligned_alloc and gets. aligned_alloc I additionally exposed with the non-standard feature test macro _ISOC11_SOURCE, for the simple reason that glibc does it; if you have a non-C11 compiler but C11 libc, -D_ISOC11_SOURCE is a much less gross way to get aligned_alloc than -D_GNU_SOURCE, anyway :) With valediction, - Gregor Richards View attachment "c11-easy.diff" of type "text/x-diff" (2398 bytes)
