Rich Felker	b5e3832f85	ppc signal/NSIG related fix (warning fix, redefinition)	14 years ago
Rich Felker	65b98213e4	add back NSIG, removed from powerpc in last commit, but for all archs unlike the previous definition, NSIG/_NSIG is supposed to be one more than the highest signal number. adding this will allow simplifying libc-internal code that makes signal-related syscalls, which can be done as a later step. some apps might use it too; while this usage is questionable, it's at least not insane.	14 years ago
Rich Felker	57a0b82441	make powerpc signal.h namespace-clean for posix/isoc also handle the non-GNUC case where alignment attribute is not available by simply omitting it. this will not cause problems except for inclusion of mcontex_t/ucontext_t in application-defined structures, since the natural alignment of the uc_mcontext member relative to the start of ucontext_t is already correct. and shame on whoever designed this for making it impossible to satisfy the ABI requirements without GNUC extensions.	14 years ago
Rich Felker	7bdf11c2c6	fix powerpc types to match abi, and some feature test issues	14 years ago
rofl0r	2df4f6f17b	fix invalid usage of mcontext_t in powerpc signal.h	14 years ago
rofl0r	3fae236e00	powerpc: handle syscall error in clone. sigsetjmp: store temporaries in jmp_buf rather than on stack.	14 years ago
Rich Felker	6c0cba819f	fix error in configure script using >/dev/null in noclobber mode	14 years ago
Rich Felker	9565a349f2	fix powerpc asm not to store data in volatile space below stack pointer it's essential to decrement the stack pointer before writing to new stack space, rather than afterwards. otherwise there is a race condition during which asynchronous code (signals) could clobber the data being stored. it may be possible to optimize the code further using stwu, but I wanted to avoid making any changes to the actual stack layout in this commit. further improvements can be made separately if desired.	14 years ago
Rich Felker	0004ea613a	fix breakage from introducing bits header for sys/io.h apparently some other archs have sys/io.h and should not break just because they don't have the x86 port io functions. provide a blank bits/io.h everywhere for now.	14 years ago
Rich Felker	61aa6324af	add port io functions to sys/io.h based on proposal by Isaac Dunham. nonexistance of bits/io.h will cause inclusion of sys/io.h to produce an error on archs that are not supposed to have it. this is probably the desired behavior, but the error message may be a bit unusual.	14 years ago
Rich Felker	f54ac2446a	add missing const on powerpc FE_DFL_ENV	14 years ago
Rich Felker	75c450cff3	fenv support for ppc, untested based on code sent to the mailing list by nsz, with minor changes.	14 years ago
Rich Felker	0b52bf5c78	fix feholdexcept -- it needs to clear exceptions after saving environment	14 years ago
Rich Felker	19b1a8453e	Merge remote-tracking branch 'nsz/math'	14 years ago
rofl0r	8d2887f884	fcntl.h: O_SEARCH was missing for powerpc put some macros that do not differ between architectures in the main header and remove from bits. restructure mips header so it has the same structure as the others.	14 years ago
Szabolcs Nagy	a764db9a08	math: use float constants in exp10f.c use the 'f' suffix when a float constant is not representable	14 years ago
Szabolcs Nagy	e93a0fe49d	math: expl.c cleanup raise overflow and underflow when necessary, fix various comments.	14 years ago
Szabolcs Nagy	ab1772c597	math: expf.c cleanup similar to exp.c cleanup: use scalbnf, don't return excess precision, drop some optimizatoins. exp.c was changed to be more consistent with expf.c code.	14 years ago
rofl0r	ae67fe1aad	ppc socket.h: add forgotten cmsghdr	14 years ago
Rich Felker	71955b2ff8	fix typo in dynamic linker path file loading code fortunately the memory corruption could not hurt anything, but it prevented clearing the final newline and thus prevented the last path element from working.	14 years ago
Rich Felker	d0197ff031	add cleaned-up sys/mtio.h this is mostly junk, but a few programs with tape-drive support unconditionally include it, and it might be useful.	14 years ago
Rich Felker	5c6443ac42	add stub versions of some missing optional pthread interfaces priority inheritance is not yet supported, and priority protection probably will not be supported ever unless there's serious demand for it (it's a fairly heavy-weight feature). per-thread cpu clocks would be nice to have, but to my knowledge linux is still not capable of supporting them. glibc fakes them by using the _process_ cpu-time clock and subtracting the thread creation time, which gives seriously incorrect semantics (worse than not supporting the feature at all), so until there's a way to do it right, it will remain as a stub that always fails.	14 years ago
Szabolcs Nagy	159c7655d0	math: cleanup exp2.c exp2f.c and exp2l.c * old code relied on sign extension on right shift * exp2l ld64 wrapper was wrong * use scalbn instead of bithacks	14 years ago
Rich Felker	bb9abdef48	arg-skipping code for powerpc dynamic linker this allows using the dynamic linker as a command to load programs.	14 years ago
Szabolcs Nagy	bbbf045ce9	math: exp.c clean up overflow and underflow was incorrect when the result was not stored. an optimization for the 0.5ln2 < \|x\| < 1.5ln2 domain was removed. did various cleanups around static constants and made the comments consistent with the code.	14 years ago
Rich Felker	a4db94ab78	dynamic linking support for powerpc incomplete but at least partly working. requires all files to be compiled in the new "secure" plt model, not the old one that put plt code in the data segment. TLS is untested but may work. invoking the dynamic linker explicitly to load a program does not yet handle argv correctly.	14 years ago
Rich Felker	7718e7cce5	fix ppc stat structure definition	14 years ago
rofl0r	3bb6bd8580	fix powerpc termios.h and ioctl.h	14 years ago
Rich Felker	91738d0241	disable SO_REUSEPORT in sys/socket.h although a number is reserved for it, this option is not implemented on Linux and does not work. defining it causes some applications to use it, and subsequently break due to its failure.	14 years ago
Rich Felker	7491bac33e	ppc wchar_t is long, not int	14 years ago
Rich Felker	8bb1816222	Merge remote-tracking branch 'nsz/math'	14 years ago
Rich Felker	22781b4d8e	update copyright file for recent contributions	14 years ago
Rich Felker	d1bf452d75	fix indention with spaces in powerpc asm	14 years ago
Rich Felker	e7257d3e63	fix powerpc atomic compare-and-swap function previous version did not compare at all; it was just a fancy atomic write. untested. further atomic fixes may be needed.	14 years ago
Rich Felker	574d01a696	update ppc atomic code to match the endian-agnostic version on other archs	14 years ago
Rich Felker	50cb6dbb0c	fix wchar limits mistakenly copied from arm	14 years ago
Rich Felker	c6d441e3a2	Merge remote-tracking branch 'ppc-port/ppc-squashed'	14 years ago
Szabolcs Nagy	68847ecd3a	fenv: return FE_TONEAREST in dummy fegetround	14 years ago
Szabolcs Nagy	45ff9d8eb6	math: ld80 invtrig cleanups keeping only commonly used data in invtrigl	14 years ago
Szabolcs Nagy	529a8de46c	math: simplify hypot and hypotf using scalbn this also fixes overflow/underflow raising and excess precision issues (as those are handled well in scalbn)	14 years ago
Szabolcs Nagy	6d3f1a39c1	math: turn off the STRICT_ASSIGN workaround by default the volatile hack in STRICT_ASSIGN is only needed if assignment is not respected and excess precision is kept. gcc -fexcess-precision=standard and -ffloat-store both respect assignment and musl use these flags by default. i kept the macro for now so the workaround may be used for bad compilers in the future.	14 years ago
rofl0r	1c8eb8bad7	PPC port cleaned up, static linking works well now.	14 years ago
Richard Pennington	7669d1e334	import preliminary ppc work by rdp.	14 years ago
Szabolcs Nagy	033a9d6ad2	math: use '#pragma STDC FENV_ACCESS ON' when fenv is accessed	14 years ago
