2020-09-30[nvptx] Add type arg to TARGET_LIBC_HAS_FUNCTIONTom de Vries1-1/+2
GCC has a target hook TARGET_LIBC_HAS_FUNCTION, which tells the compiler which functions it can expect to be present in libc. The default target hook does not include the sincos functions. The nvptx port of newlib does include sincos and sincosf, but not sincosl. The target hook TARGET_LIBC_HAS_FUNCTION does not distinguish between sincos, sincosf and sincosl, so if we enable it for the sincos functions, then for test.c: ... long double x, a, b; int main (void) { x = 0.5; a = sinl (x); b = cosl (x); printf ("a: %f\n", (double)a); printf ("b: %f\n", (double)b); return 0; } ... we introduce a regression: ... $ gcc test.c -lm -O2 unresolved symbol sincosl collect2: error: ld returned 1 exit status ... Add a type argument to target hook TARGET_LIBC_HAS_FUNCTION_TYPE, and use it in nvptx_libc_has_function_type to enable sincos and sincosf, but not sincosl. Build and reg-tested on x86_64-linux.
