2024-04-30Define __USE_TIME_BITS64 when it is necessary.Dmitry Chestnykh
Glibc and musl both defines this macro. Glibc defines it for 64-bit time_t on 32-bit arch and for 64-bit architectures. Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>
2024-04-24Makerules: fix out-of-tree build error "Argument list too long"Max Filippov
Make rule that announces and makes static libc archive can generate command line that is too long when a full path O= option is used. That breaks the build with the following message: make: /bin/sh: Argument list too long Use make $(file) construct to generate file list file and use that file as $(AR) argument instead.

2024-04-24fix out-of-tree build with UCLIBC_HAS_CONTEXT_FUNCSMax Filippov
When building libc out-of-tree *context functions cannot find generated header ucontext_i.h: libc/sysdeps/linux/xtensa/setcontext.S:19:10: fatal error: ucontext_i.h: No such file or directory Fix that by adding include path to the build directory with that file to the compiler flags.

2024-04-20x86: Fix __libc_sigaction implementation.Dmitry Chestnykh
For x86 we have to copy only mask, handler and flags. We haven't set SA_RESTORER bit in sa_flags anyway. This patch fixes multiple test failures on x86. Also we have to build uClibc with FP for x86 because without FP NPTL and libgcc code cannot properly unwind the stack during asynchronous cancellation of system calls.

2024-04-20Switch x86 NPTL impl to generic C code.Dmitry Chestnykh
The asm code has high maintainance cost. The cost is extremely high if we take into consideration time64 implementation which implies operating with 64bit numbers on 32bit system. Also glibc uses mainly C in NPTL code. Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>
2024-04-18aarch64: Apply relocations to use TLS GD access model.Dmitry Chestnykh
In aarch64 when the general dynamic access model is used for tls data the linker emits two dynamic relocs (R_AARCH64_TLS_DTPMOD(64) and R_AARCH64_TLS_DTPREL(64)) that must be applied by ld.so during object loading. Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>

2024-04-18Generalize vDSO code.Dmitry Chestnykh
- Add macroses for vDSO functions names because in some architectures these names differ from the default ones. - Add header guards in dl-syscalls.h . Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>
2024-04-18Fix vDSO support for all supported architectures.Dmitry Chestnykh
- Cleanup dl-vdso.c code. - Pass `void *` as first arg to `load_vdso()`, using 32-bit type is completely wrong on 64bit architectures. - Split libc code and vDSO-related code. Move arch-specific implementations into separate files. The performance improvement is for example 50-60 times on ARMv7 and about 4 times on x86_64.

2024-04-14libuargp: restrict compatibility macros in argp.h onlyYao Zi
Macros __attribute__, __format__ and __printf__ are defined in argp.h for compatibility with ANSI and old gccs. But leaving them effective out of the scope of the header may break applications relying on these compiler attributes even with __STRICT_ANSI__ defined. So undef the macros after using.

2024-04-13Provide fixups for riscv32.Dmitry Chestnykh
- Use TIME64 by default for rv32, usage of 32-bit time leads to a lot of incompatibilities with linux kernel 6.6.x and later versions. - Add some other corrections to use proper system calls on riscv32 platform. Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>
