It allows also to remove hppa specific implementation and simplify riscv implementation a bit.
2021-05-10Linux: Explicitly disable cancellation checking in the dynamic loaderFlorian Weimer1-2/+9
Historically, SINGLE_THREAD_P is defined to 1 in the dynamic loader. This has the side effect of disabling cancellation points. In order to enable future use of SINGLE_THREAD_P for single-thread optimizations in the dynamic loader (which becomes important once more code is moved from libpthread), introduce a new NO_SYSCALL_CANCEL_CHECKING macro which is always 1 for IS_IN (rtld), indepdently of the actual SINGLE_THREAD_P value.

2020-02-14linux: Remove INTERNAL_SYSCALL_DECLAdhemerval Zanella1-18/+18
With all Linux ABIs using the expected Linux kABI to indicate syscalls errors, the INTERNAL_SYSCALL_DECL is an empty declaration on all ports. This patch removes the 'err' argument on INTERNAL_SYSCALL* macro and remove the INTERNAL_SYSCALL_DECL usage. Checked with a build against all affected ABIs.

2018-07-24nptl: Add C11 threads thrd_* functionsAdhemerval Zanella1-0/+16
This patch adds the thrd_* definitions from C11 threads (ISO/IEC 9899:2011), more specifically thrd_create, thrd_curent, rhd_detach, thrd_equal, thrd_exit, thrd_join, thrd_sleep, thrd_yield, and required types. Mostly of the definitions are composed based on POSIX conterparts, such as thrd_t (using pthread_t). For thrd_* function internally direct POSIX pthread call are used with the exceptions: 1. thrd_start uses pthread_create internal implementation, but changes how to actually calls the start routine. This is due the difference in signature between POSIX and C11, where former return a 'void *' and latter 'int'. To avoid calling convention issues due 'void *' to int cast, routines from C11 threads are started slight different than default pthread one. Explicit cast to expected return are used internally on pthread_create and the result is stored back to void also with an explicit cast. 2. thrd_sleep uses nanosleep internal direct syscall to avoid clobbering errno and to handle expected standard return codes. It is a cancellation entrypoint to be consistent with both thrd_join and cnd_{timed}wait. 3. thrd_yield also uses internal direct syscall to avoid errno clobbering. Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabi, i386-linux-gnu, ia64-linux-gnu, m68k-linux-gnu, microblaze-linux-gnu [1], mips{64}-linux-gnu, nios2-linux-gnu, powerpc{64le}-linux-gnu, s390{x}-linux-gnu, sparc{64}-linux-gnu, and x86_64-linux-gnu).

2016-09-26Add INTERNAL_SYSCALL_CALLAdhemerval Zanella1-18/+55
This patch adds two new macros for internal and inline syscall to use within GLIBC: INTERNAL_SYSCALL_CALL and INLINE_SYSCALL_CALL. They are similar to the old INTERNAL_SYSCALL and INLINE_SYSCALL with the difference the new macros accept a variable argument call and do not require to pass the expected argument size. The advantage is it is possible to use variable argument macros like SYSCALL_LL{64} without the need to also handle the argument size. So for an ABI where SYSCALL_LL might split the argument in high and low parts, instead of: INTERNAL_SYSCALL_DECL (err); #if ... INTERNAL_SYSCALL (syscall, err, 2, SYSCALL_LL (len)); #else INTERNAL_SYSCALL (syscall, err, 1, SYSCALL_LL (len)); #endif It will be just: INTERNAL_SYSCALL_CALL (syscall, err, SYSCALL_LL (len)); The INLINE_SYSCALL_CALL follows the same semanthic regarding the argument and is similar to INLINE_SYSCALL regarding setting errno. Checked with a build for x86_64, i386, aach64, armhf, powerpc64le, powerpc32, and mips32. No code generation changed. * sysdeps/unix/sysdep.h (__INTERNAL_SYSCALL0): New macro.

2015-08-21Revert "Add INLINE_SYSCALL_RETURN/INLINE_SYSCALL_ERROR_RETURN"H.J. Lu1-19/+0
This reverts commit 0c5b8b5941e036dcaac69cecee9f01fdf9218e6e.
2015-08-21Add INLINE_SYSCALL_RETURN/INLINE_SYSCALL_ERROR_RETURNH.J. Lu1-0/+19
For ia32 PIC, the first thing of many syscalls does is to call __x86.get_pc_thunk.reg to load PC into reg in case there is an error, which is required for setting errno. In most cases, there are no errors. But we still call __x86.get_pc_thunk.reg. This patch adds INLINE_SYSCALL_RETURN and INLINE_SYSCALL_ERROR_RETURN so that i386 can optimize setting errno by branching to the internal __syscall_error without PLT. INLINE_SYSCALL_ERROR_RETURN is designed to take the negative error number returned from the majority of Linux kernels for which negating is a no-op with INTERNAL_SYSCALL_ERRNO.

Mon Jun 10 17:50:31 1996 David Mosberger-Tang <davidm@azstarnet.com> * sysdeps/unix/sysv/linux/alpha/pipe.S: Use PSEUDO. * sysdeps/unix/sysv/linux/alpha/sysdep.S, sysdeps/unix/sysv/linux/alpha/brk.S, sysdeps/unix/sysv/linux/alpha/ieee_get_fp_control.S, sysdeps/unix/sysv/linux/alpha/ieee_set_fp_control.S, sysdeps/unix/sysv/linux/alpha/llseek.S, sysdeps/unix/sysv/linux/alpha/sigsuspend.S, sysdeps/unix/sysv/linux/alpha/syscall.S: Rename syscall_error to __syscall_error to avoid intruding application name space. * sysdeps/unix/sysv/linux/alpha/sysdep.h: Rename __NR_get?id to SYS_get?id so that syscall stubs in sysdeps/unix define these syscalls in terms of getxpid/getxuid/getxgid. * sysdeps/unix/_exit.S, sysdeps/unix/getegid.S, sysdeps/unix/geteuid.S, sysdeps/unix/getppid.S, sysdeps/unix/execve.S, sysdeps/unix/fork.S, sysdeps/unix/syscall.S: Terminate syscall with PSEUDO_END. * sysdeps/unix/make-syscalls.sh, sysdeps/unix/sysdep.h (PSEUDO_END): Rename END() to PSEUDO_END(). * sysdeps/unix/alpha/sysdep.h: Move error-handling code in PSEUDO to PSEUDO_END to improve branch-prediction.

(PSEUDO_END): New macro. * sysdeps/unix/alpha/sysdep.h, sysdeps/alpha/bb_init_func.S, sysdeps/unix/sysv/linux/alpha/brk.S: Use ldiq instead of ldi since latter is illegal under DEC Unix. * sysdeps/unix/alpha/sysdep.S: Renamed from sysdeps/unix/sysv/linux/alpha/sysdep.S. This file works for OSF/1 as well. * sysdeps/unix/bsd/osf/alpha/sysdep.S: Remove (note that the EWOULDBLOCK -> EAGAIN mapping was unnecessary since EWOULDBLOCK==EAGAIN under DEC Unix and Linux/Alpha). * sysdeps/alpha/divrem.h: Use retaddr instead of ra as the return address register in the .frame directive. * sysdeps/alpha/copysign.c: Remove. * sunrpc/rpc/types.h: Include <sys/param.h> and <netinet/in.h> to avoid RPC definitions of INADDR_LOOPBACK and/or MAXHOSTNAMELEN. * errno.h: Move __END_DECLS to correct place to make file compilable under c++. * dirent/dirent.h: Document _DIRENT_HAVE_D_OFF macro. Define d_ino only if <direntry.h> hasn't defined d_fileno. * configure.in (HAVE_ASM_WEAKEXT_DIRECTIVE): Reverse order of arguments to weakext to make .weakext detection work on ECOFF systems. * FAQ: Add Linux/Alpha to list of supported platforms. Mention that _validuser() has been replaced by __ivaliduser(). Thu Jun 6 21:39:38 1996 David Mosberger-Tang <davidm@azstarnet.com> * sysdeps/unix/bsd/sun/sunos4/tcsetattr.c (tcsetattr): Declare cmd as unsigned long, not as int (to avoid incorrect int->long promotion).

* time/Makefile (tests): Add test-tz. * time/test-tz.c: New test. * time/clocktest.c: Rewrite to test more meaningfully. * sysdeps/unix/sysv/linux/syscalls.list: Add bdflush, create_module, delete_module, get_kernel_syms, init_module, klogctl. * sysdeps/unix/sysv/linux/sys/param.h (MAXSYMLINKS): Define as 5 instead of SYMLOOP_MAX, which is nowhere to be found. * sysdeps/unix/sysv/linux/sys/msq_buf.h, sysdeps/unix/sysv/linux/sys/sem_buf.h, sysdeps/unix/sysv/linux/sys/shm_buf.h [__USE_MISC]: Add more control ops and datastructures. * sysdeps/unix/sysv/linux/sys/io.h: New file declaring low-level I/O related functions. * sysdeps/unix/sysv/linux/sys/kdaemon.h: New file declaring kernel daemon related functions/operations. * sysdeps/unix/sysv/linux/sys/klog.h: New file declaring kernel logging related functions/operations. * sysdeps/unix/sysv/linux/sys/module.h: New file declaring kernel module related functions/operations. * sysdeps/unix/sysv/linux/speed.c: Only do "mention this twice" hack for non-Alpha based Linux systems. * sysdeps/unix/sysv/linux/alpha/speed.c: Remove. * sysdeps/unix/sysv/linux/Makefile (headers): Add sys/module.h, sys/io.h, sys/klog.h, and sys/kdaemon.h. * sysdeps/unix/sysdep.h (END): Define empty END macro for platforms that don't need some sort of end directive at the end of functions. * sysdeps/unix/make-syscalls.sh: Emit END($strong) at end of syscall wrapper to allow correct generation of debugging information. * sysdeps/unix/alpha/sysdep.h (END): Redefine to use .end directive for both ELF and ECOFF. (ret): Delete macro. It was a dangerous macro and unnecessary since the Alpha assemblers recognizes "ret" as a macro themselves. * sysdeps/gnu/utmpbits.h (struct utmp): Move ut_tv behind ut_session to guarantee long alignment. This is important for Linux/Alpha since ut_tv.tv_sec is 32 bits and time_t is 64 bits. This will all get cleaned up as programs start to use ut_tv instead ut_time. * sysdeps/alpha/divrem.h: Include <sysdep.h> instead of <*/regdef.h>. * sysdeps/alpha/bsd-_setjmp.S (setjmp): Renamed entry point to _setjmp. * sysdeps/alpha/_mcount.S, sysdeps/alpha/bb_init_func.S, sysdeps/alpha/bsd-_setjmp.S, sysdeps/alpha/bsd-setjmp.S, sysdeps/alpha/copysign.S, sysdeps/alpha/divrem.h, sysdeps/alpha/fabs.S, sysdeps/alpha/ffs.S, sysdeps/alpha/htonl.S, sysdeps/alpha/htons.S, sysdeps/alpha/memchr.S, sysdeps/alpha/setjmp.S, sysdeps/alpha/strlen.S, sysdeps/unix/sysv/linux/alpha/ieee_get_fp_control.S, sysdeps/unix/sysv/linux/alpha/ieee_set_fp_control.S, sysdeps/unix/sysv/linux/alpha/llseek.S, sysdeps/unix/sysv/linux/alpha/pipe.S, sysdeps/unix/sysv/linux/alpha/sigsuspend.S, sysdeps/unix/sysv/linux/alpha/sysdep.S: Use END macro instead of .end directive. * csu/initfini.c (_fini): Tell gcc that _fini is not a leaf function by having it contain a dummy function call. * configure.in (config_machine): Don't make ELF the default for Linux/Alpha just yet (use --with-elf instead). (.init/.fini check): Generate .text to ensure function start and end are in same section. * sysdeps/unix/bsd/osf/alpha/brk.S, sysdeps/unix/sysv/linux/alpha/brk.S (__curbrk): Store the entire break value, not just the low 32 bits to accomodate large memories. Tue May 28 10:46:04 1996 Richard Henderson <rth@tamu.edu> * sysdeps/unix/sysv/linux/alpha/brk.S: Rather than attempt to dynamically resolve _end for initializing __curbrk, support the brk(0) query idiom. * sysdeps/alpha/bb_init_func.S: Don't make `init' an external symbol. * sysdeps/alpha/bsd-_setjmp.S: The function is _setjmp not setjmp. Sun May 26 22:17:38 1996 Richard Henderson <rth@tamu.edu> * stdlib/lcong48_r.c, stdlib/seed48_r.c, stdlib/strtod.c, stdlib/strtol.c: Include <string.h> for mem* and str* fns used. Thu May 23 02:15:56 1996 David Mosberger-Tang <davidm@azstarnet.com> * sysdeps/unix/sysv/linux/Makefile (headers): Add sys/io.h, sys/klog.h, and sys/kdaemon.h. * sysdeps/unix/sysv/linux/sys/io.h: New file. * sysdeps/unix/sysv/linux/sys/klog.h: Ditto. * sysdeps/unix/sysv/linux/sys/kdaemon.h: Ditto. * sysdeps/unix/alpha/sysdep.h (ret): Remove macro. It is dangerous and unnecessary since both OSF/1 as and gas define "ret" as a pseudo-instruction. Sat Jun 1 17:18:21 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * time/tzset.c (__tzset): Clear tz_rules name pointers after freeing them. Bug found by David Mosberger-Tang. * sysdeps/posix/tempname.c (__stdio_gen_tempname): Use __ptr_t instead of PTR. * extra-lib.mk (extra-objs): Use patsubst intead of $(A:=B) syntax to work around Make bug when A contains var ref. Fri May 31 18:27:52 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * string/string.h [__USE_MISC]: Declare basename; OSF/1 puts it here. * sysdeps/unix/sysv/linux/syscalls.list (getpgid, setpgid): Define __ strong names and [gs]etpgid as weak aliases. * math/math_private.h (GET_LDOUBLE_EXP): Add missing backslash.

* malloc/malloc.c (morecore): Don't attempt recursive realloc of info table when _heaplimit==0 during realloc growing large block. * MakeTAGS (extract): Remove /dev/null from xgettext command line. (text-srcs): New variable: extract only C sources from $(tags_sources). (po/$(domain).pot): Depend on that. If it's empty, cp /dev/null $@ instead of $(extract). * misc/Makefile (headers): Add iovec.h. * sysdeps/unix/sysv/linux/iovec.h: New file. * sysdeps/generic/iovec.h: New file. * misc/sys/uio.h (struct iovec): Type replaced with #include <iovec.h>. * configure.in (NO_UNDERSCORES check): Use AC_TRY_LINK instead of AC_TRY_COMPILE. * misc/sys/cdefs.h [__USE_BSD] (const, signed, volatile): Move these macros inside [! __STDC__]. * stdlib/rpmatch.c: New file. * stdlib/Makefile (routines): Add rpmatch. * stdlib/stdlib.h [__USE_SVID]: Declare rpmatch. * MakeTAGS (MSGJOIN): Variable removed. (po/SYS_libc.pot): Use $(XGETTEXT) instead of $(MSGJOIN). Wed Mar 20 20:08:46 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/unix/sysdep.h: Don't define C_SYMBOL_NAME. * sysdeps/unix/sysv/linux/m68k/sysdep.h: Don't define NO_UNDERSCORES.
