2024-06-15libc: cast free() argument to void * in wchar.cYuriy Kolerov
iconv_close() accepts iconv_t type (which is void *) and passes it to free() which accepts void *. However, GCC 14 raises a -Wint-conversion warning if it is not casted to void * because GCC cannot unwind typedef of iconv_t. Signed-off-by: Yuriy Kolerov <ykolerov@synopsys.com>

2024-05-21xtensa: make _init and _fini hiddenMax Filippov
Make _init and _fini hidden so that references to these symbols bind locally in the shared objects. glibc does the same. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
2024-05-21xtensa: use compiler-provided XCHAL macrosMax Filippov
Starting with gcc-13 the compiler provides configuration-specific macro definitions for the target xtensa core. Use them when available instead of the configuration overlay file xtensa-config.h Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

2024-05-16Correct uClibc compilation.Dmitry Chestnykh
- Include sys/types.h instead of asm/types.h to prevent types conflict for uClibc typedefs and kernel headers typedefs. - Cast 3rd arg of utimensat_time64 syscall to integer type to avoid compiler's -Wint-conversion error. The error was found during uClibc compilation for mips32. Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>

With gcc-14 warnings caused by type mismatches turn to errors: - got_entry is a pointer in the _dl_linux_resolver(), but the function _dl_linux_resolver() returns unsigned long. Convert got_entry to unsigned long when returning - first argument of _dl_funcdesc_for() is a pointer, but (symbol_addr + reloc_value) is unsigned long in the _dl_do_reloc(). Convert function argument to (void *) - struct funcdesc_value::entry_point is a pointer, but DL_RELOC_ADDR returns ElfW(Addr). Convert DL_RELOC_ADDR result to (void *) before assigning to funcdesc_value::entry_point Signed-off-by: Max Filippov <jcmvbkbc@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.

Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>
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>

2024-04-18Fix 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.

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.
