2024-04-17Undef attribute_relro on internal tests that include tls.hAdhemerval Zanella3-0/+6
So it does not clash with global definition.
2024-04-17elf: Do not cast TLS_DTV_UNALLOCATED to voidAdhemerval Zanella6-7/+6
The test-as-const-tlsdesc uses _Static_assert to verify the constants generated and clang warns the expression is not an integral constant expression because the cast performs a conversion (and it is no allowed).

2024-04-17x86: Use inhibit_stack_protector on tst-ifunc-isa.hAdhemerval Zanella1-2/+3
2024-04-17Move inhibit_stack_protector to its own headerAdhemerval Zanella2-14/+39
It is used on tests as well.

2024-04-17posix: Suppress clang warning on bug-regex24Adhemerval Zanella1-0/+7
clang complains that adding a 'regoff_t' to a string doe snot append to it, and the printf idea below is to make rm_so an offset.

2024-04-17x86_64: Disable libmvec tests if compiler does not support attribute '__simd__'Adhemerval Zanella3-0/+93
clang ignore the attribute, which is required by libmvec tests.
2024-04-17math: Only build tests for _Complex __int128 iff compiler supports itAdhemerval Zanella4-10/+76
clang fails building test-tgmath3-atan2.c: error: '_Complex __int128' is invalid _Complex __int128 var__Complex___int128 __attribute__ ((unused)); since it does not support _Complex with __int128. So disable the test in such case.
2024-04-17x86: Fix test-double-vlen include-nextAdhemerval Zanella4-4/+4
clang issues: ../sysdeps/x86_64/fpu/test-double-vlen4.h:20:2: error: #include_next in file found relative to primary source file or found by absolute path; will search from start of include path [-Werror,-Winclude-next-absolute-path] Instead of suppress the warning, it is simpler to just include the absolute path instead.

2024-04-17math: Fix clang warnings on bug-tgmath1.cAdhemerval Zanella1-0/+7
The type generic fabs expansion issues the floating point absolute with the wrong argument type (for instance cabs with floating point or fabs with a complex type) and clang warns that implicit conversion might incur in unexpected behavior.
2024-04-17math: Fix clang warnings for math/test-tgmath-ret.cAdhemerval Zanella1-0/+6
clang warns that since the global variables are only used to function calls (without being actually used), there are not needed and will not be emitted.
2024-04-17localedata: Fix clang warnings on testsAdhemerval Zanella1-1/+7
clang does not support 'I' specifier and handles it as a 'length modifier'.
2024-04-17configure: remove overly restrictive check for clangFangrui Song2-4/+4
2024-04-17riscv: Suppress clang confstr -Wignored-attributes feupdateenvAdhemerval Zanella1-0/+6
clang warns that the alias will be always resolve to __GI___feupdateenv even if weak definition of __GI_feupdateenv is overridden, which is really the intention.
2024-04-17riscv: Do not use cfi_label when building with clangAdhemerval Zanella4-3/+9
The .cfi_label is a gas extension not supported by clang. From a ziglang discussion [1], it seems that it is not really required. [1] https://github.com/ziglang/zig/issues/3340
2024-04-17string: Suppress clang confstr -Wignored-attributes on strlenAdhemerval Zanella1-0/+5
clang warns that the alias will be always resolve to __strlen even if weak definition of __GI_strlen is overridden, which is really the intention.
2024-04-17arm: Fix clang multi-arch build with ld.bfdAdhemerval Zanella5-13/+8
clang binds autogenerated memcpy/memset/memchr calls to the hidden internal symbols, different than gcc that binds without hidden attribute. And this triggers an linker issue with bfd: ld: BFD (GNU Binutils for Ubuntu) 2.38 assertion fail ../../bfd/elf32-arm.c:4286 Similar to other architectures, bind internal memcpy and memcpy symbols to the generic interface instead.
2024-04-17arm: Use vmov.i32 instead of vmov on neon memchrAdhemerval Zanella1-2/+2
clang fails with: error: invalid instruction
2024-04-17aarch64: Use 64-bit variable to access the special registersAdhemerval Zanella5-15/+29
clang issues: error: value size does not match register size specified by the constraint and modifier [-Werror,-Wasm-operand-widths] while tryng to use 32 bit variables with 'mrs' to get/set the fpsr, dczid_el0, and ctr. Since all of 64 bit register, use the expected variable size.
2024-04-17i386: sfp-machine.h: Do no use asm input cast for clangAdhemerval Zanella1-18/+26
clang by default rejects the input casts with: error: invalid use of a cast in a inline asm context requiring an lvalue: remove the cast or build with -fheinous-gnu-extensions And even with -fheinous-gnu-extensions clang still throws an warning and also states that this option might be removed in the future. For gcc the cast are still useful [1] as type-checking. [1] https://gcc.gnu.org/pipermail/gcc-patches/2021-October/581722.html
2024-04-17i386: Move ___tls_get_addr hidden proto before its first usageAdhemerval Zanella1-2/+2
clang can not apply asm redirections to functions after these functions are used for the first time.
2024-04-17i386: Disable math_opt_barrier and math_force_eval for clangAdhemerval Zanella1-1/+1
It triggers an ICE with clang while building round_and_return.

2024-04-17x86: math: Avoid the use of __libgcc_cmp_return__ for __gcc_CMPtypeAdhemerval Zanella1-2/+11
2024-04-17x86: Define __HAVE_FLOAT128 for Clang and use __builtin_*f128 code pathFangrui Song1-7/+14
Clang supports __builtin_fabsf128 (despite not supporting _Float128) but it does not support __builtin_fabsq. Fallback to back to `typedef __float128 _Float128;` it clang is used.
2024-04-17x86: Use -msse2avx iff compiler supports itAdhemerval Zanella3-7/+40

2024-04-17stdio: Fix -Wtautological-constant-out-of-range-compare on clangAdhemerval Zanella1-1/+6
clang emits an error while building vfprintf-internal for default case: error: result of comparison of constant 255 with expression of type 'char' is always true [-Werror,-Wtautological-constant-out-of-range-compare] if (spec <= UCHAR_MAX The test is indeed not required for default non-wide build.
