* remove LFS64 symbol aliases; replace with dynamic linker remappingRich Felker2022-10-191-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | originally the namespace-infringing "large file support" interfaces were included as part of glibc-ABI-compat, with the intent that they not be used for linking, since our off_t is and always has been unconditionally 64-bit and since we usually do not aim to support nonstandard interfaces when there is an equivalent standard interface. unfortunately, having the symbols present and available for linking caused configure scripts to detect them and attempt to use them without declarations, producing all the expected ill effects that entails. as a result, commit 2dd8d5e1b8ba1118ff1782e96545cb8a2318592c was made to prevent this, using macros to redirect the LFS64 names to the standard names, conditional on _GNU_SOURCE or _LARGEFILE64_SOURCE. however, this has turned out to be a source of further problems, especially since g++ defines _GNU_SOURCE by default. in particular, the presence of these names as macros breaks a lot of valid code. this commit removes all the LFS64 symbols and replaces them with a mechanism in the dynamic linker symbol lookup failure path to retry with the spurious "64" removed from the symbol name. in the future, if/when the rest of glibc-ABI-compat is moved out of libc, this can be removed.
* remove spurious inclusion of libc.h for LFS64 ABI aliasesRich Felker2018-09-121-2/+1
| | | | | | the LFS64 macro was not self-documenting and barely saved any characters. simply use weak_alias directly so that it's clear what's being done, and doesn't depend on a header to provide a strange macro.
* update syscalls with off_t arguments to handle argument alignment, if neededRich Felker2011-09-211-1/+1
| | | | | | the arm syscall abi requires 64-bit arguments to be aligned on an even register boundary. these new macros facilitate meeting the abi requirement without imposing significant ugliness on the code.
* consistency: change all remaining syscalls to use SYS_ rather than __NR_ prefixRich Felker2011-04-061-1/+1

* syscall overhaul part two - unify public and internal syscall interfaceRich Felker2011-03-191-1/+1
| | | | | | | | | | | | | | | | with this patch, the syscallN() functions are no longer needed; a variadic syscall() macro allows syscalls with anywhere from 0 to 6 arguments to be made with a single macro name. also, manually casting each non-integer argument with (long) is no longer necessary; the casts are hidden in the macros. some source files which depended on being able to define the old macro SYSCALL_RETURNS_ERRNO have been modified to directly use __syscall() instead of syscall(). references to SYSCALL_SIGSET_SIZE and SYSCALL_LL have also been changed. x86_64 has not been tested, and may need a follow-up commit to fix any minor bugs/oversights.
