in the previous commit sse fenv support was added, but there is no need to save mxcsr (sse fenv register) so fix the abi incompatibility with glibc.

this is necessary to meet the C++ ABI target. alternatives were considered to avoid the size increase for non-sig jmp_buf objects, but they seemed to have worse properties. moreover, the relative size increase is only extreme on x86[_64]; one way of interpreting this is that, if the size increase from this patch makes jmp_buf use too much memory, then the program was already using too much memory when built for non-x86 archs.

rather than moving nlink_t back to the arch-specific file, I've added a macro _Reg defined to the canonical type for register-size values on the arch. this is not the same as _Addr for (not-yet-supported) 32-on-64 pseudo-archs like x32 and mips n32, so a new macro was needed.

aside from the obvious C++ ABI purpose for this change, it also brings musl into alignment with the compiler's idea of the definition of wint_t (use in -Wformat), and makes the situation less awkward on ARM, where wchar_t is unsigned. internal code using wint_t and WEOF was checked against this change, and while a few cases of storing WEOF into wchar_t were found, they all seem to operate properly with the natural conversion from unsigned to signed.

the arch-specific bits/alltypes.h.sh has been replaced with a generic alltypes.h.in and minimal arch-specific bits/alltypes.h.in. this commit is intended to have no functional changes except: - exposing additional symbols that POSIX allows but does not require - changing the C++ name mangling for some types - fixing the signedness of blksize_t on powerpc (POSIX requires signed) - fixing the limit macros for sig_atomic_t on x86_64 - making dev_t an unsigned type (ABI matching goal, and more logical) in addition, some types that were wrongly defined with long on 32-bit archs were changed to int, and vice versa; this change is non-functional except for the possibility of making pointer types mismatch, and only affects programs that were using them incorrectly, and only at build-time, not runtime. the following changes were made in the interest of moving non-arch-specific types out of the alltypes system and into the headers they're associated with, and also will tend to improve application compatibility: - netdb.h now includes netinet/in.h (for socklen_t and uint32_t) - netinet/in.h now includes sys/socket.h and inttypes.h - sys/resource.h now includes sys/time.h (for struct timeval) - sys/wait.h now includes signal.h (for siginfo_t) - langinfo.h now includes nl_types.h (for nl_item) for the types in stdint.h: - types which are of no interest to other headers were moved out of the alltypes system. - fast types for 8- and 64-bit are hard-coded (at least for now); only the 16- and 32-bit ones have reason to vary by arch. and the following types have been changed for C++ ABI purposes; - mbstate_t now has a struct tag, __mbstate_t - FILE's struct tag has been changed to _IO_FILE - DIR's struct tag has been changed to __dirstream - locale_t's struct tag has been changed to __locale_struct - pthread_t is defined as unsigned long in C++ mode only - fpos_t now has a struct tag, _G_fpos64_t - fsid_t's struct tag has been changed to __fsid_t - idtype_t has been made an enum type (also required by POSIX) - nl_catd has been changed from long to void * - siginfo_t's struct tag has been removed - sigset_t's has been given a struct tag, __sigset_t - stack_t has been given a struct tag, sigaltstack - suseconds_t has been changed to long on 32-bit archs - [u]intptr_t have been changed from long to int rank on 32-bit archs - dev_t has been made unsigned summary of tests that have been performed against these changes: - nsz's libc-test (diff -u before and after) - C++ ABI check symbol dump (diff -u before, after, glibc) - grepped for __NEED, made sure types needed are still in alltypes - built gcc 3.4.6

this change is both to fix one of the remaining type (and thus C++ ABI) mismatches with glibc/LSB and to allow use of the full range of uid and gid values, if so desired. passwd/group access functions were not prepared to deal with unsigned values, so they too have been fixed with this commit.

despite declaring functions that take arguments of type va_list, these headers are not permitted by the c standard to expose the definition of va_list, so an alias for the type must be used. the name __isoc_va_list was chosen to convey that the purpose of this alternate name is for iso c conformance, and to avoid the multitude of names which gcc mangles with its hideous "fixincludes" monstrosity, leading to serious header breakage if these "fixes" are run.

previously we were using an unsigned type on 32-bit systems so that subtraction would be well-defined when it wrapped, but since wrapping is non-conforming anyway (when clock() overflows, it has to return -1) the only use of unsigned would be to buy a little bit more time before overflow. this does not seem worth having the type vary per-arch (which leads to more arch-specific bugs) or disagree with the ABI musl (mostly) follows.

there was some question as to how many decimal places to use, since one decimal place is always sufficient to identify the smallest denormal uniquely. for now, I'm following the example in the C standard which is consistent with the other min/max macros we already had in place.

the preprocessor can reliably determine the signedness of wchar_t. L'\0' is used for 0 in the expressions so that, if the underlying type of wchar_t is long rather than int, the promoted type of the expression will match the type of wchar_t.

wctype_t was incorrectly "int" rather than "long" on x86_64. not only is this an ABI incompatibility; it's also a major design flaw if we ever wanted wctype_t to be implemented as a pointer, which would be necessary if locales support custom character classes, since int is too small to store a converted pointer. this commit fixes wctype_t to be unsigned long on all archs, matching the LSB ABI; this change does not matter for C code, but for C++ it affects mangling. the same issue applied to wctrans_t. glibc/LSB defines this type as const __int32_t *, but since no such definition is visible, I've just expanded the definition, int, everywhere. it would be nice if these types (which don't vary by arch) could be in wctype.h, but the OB XSI requirement in POSIX that wchar.h expose some types and functions from wctype.h precludes doing so. glibc works around this with some hideous hacks, but trying to duplicate that would go against the intent of musl's headers.

they were accidentally exposed under just baseline POSIX, which is a big namespace pollution issue. thankfully glibc only exposes them under _GNU_SOURCE, not under any of its other options, so omitting the pollution in the default _BSD_SOURCE profile does not hurt application compatibility at all.

glibc exposes them from ucontext.h. since that header includes signal.h, it is safe to put them into bits/signal.h, if _GNU_SOURCE is defined.

these structures are purely for use by trace/debug tools and tools working with core files. the definition of fpregset_t, which was previously here, has been removed because it was wrong; fpregset_t should be the type used in mcontext_t, not the type used in ptrace/core stuff.

with these changes, the members/types of mcontext_t and related stuff should closely match the glibc definitions. unlike glibc, however, the definitions here avoid using typedefs as much as possible and work directly with the underlying types, to minimize namespace pollution from signal.h in the default (_BSD_SOURCE) profile. this is a first step in improving compatibility with applications which poke at context/register information -- mainly debuggers, trace utilities, etc. additional definitions in ucontext.h and other headers may be needed later. if feature test macros are used to request a conforming namespace, mcontext_t is replaced with an opaque structure of the equivalent size and alignment; conforming programs cannot examine its contents anyway.

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.

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.
-
由 Rich Felker 提交于
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.

I'm not 100% sure that Linux's O_PATH meets the POSIX requirements for O_SEARCH, but it seems very close if not perfect. and old kernels ignore it, so O_SEARCH will still work as desired as long as the caller has read permissions to the directory.

now public syscall.h only exposes __NR_* and SYS_* constants and the variadic syscall function. no macros or inline functions, no __syscall_ret or other internal details, no 16-/32-bit legacy syscall renaming, etc. this logic has all been moved to src/internal/syscall.h with the arch-specific parts in arch/$(ARCH)/syscall_arch.h, and the amount of arch-specific stuff has been reduced to a minimum. changes still need to be reviewed/double-checked. minimal testing on i386 and mips has already been performed.

while musl itself requires a c99 compiler, some applications insist on being compiled with c89 compilers, and use of "inline" in the headers was breaking them. much of this had been avoided already by just skipping the inline keyword in pre-c99 compilers or modes, but this new unified solution is cleaner and may/should result in better code generation in the default gcc configuration.
