2007-07-12 Jakub Jelinek <jakub@redhat.com> [BZ #4775] * math/tgmath.h (__tgmath_real_type_sub): Formatting. (__tgmath_real_type): Fix if expr is const int or other const qualified integral type. (__TGMATH_UNARY_REAL_ONLY): Rewritten to avoid using statement expressions and handle const qualified arguments. (__TGMATH_BINARY_FIRST_REAL_ONLY, __TGMATH_UNARY_REAL_IMAG, __TGMATH_UNARY_REAL_IMAG_RET_REAL): Likewise. (__TGMATH_UNARY_REAL_RET_ONLY): Rewritten to avoid using statement expressions. (__TGMATH_BINARY_REAL_ONLY, __TGMATH_TERNARY_FIRST_SECOND_REAL_ONLY, __TGMATH_TERNARY_REAL_ONLY, __TGMATH_BINARY_REAL_IMAG): Likewise. (__TGMATH_UNARY_IMAG): Define. (conj, cproj): Use __TGMATH_UNARY_IMAG macro. * math/Makefile (tests): Add test-tgmath2. (CFLAGS-test-tgmath2.c): Add. * math/test-tgmath.c (fy, dy, ly, fz, dz, lz, count_cdouble, count_cfloat, count_cldouble): New variables. (NCCALLS): Define. (main): Check number of complex calls as well. (F(compile_test)): Add complex tests and tests with const qualified arguments. (y, z, ccount): Define. (F(cacos), F(casin), F(catan), F(ccos), F(csin), F(ctan), F(cacosh), F(casinh), F(catanh), F(ccosh), F(csinh), F(ctanh), F(cexp), F(clog), F(csqrt), F(cpow), F(cabs), F(carg), F(creal), F(cimag), F(conj), F(cproj)): New functions. * math/test-tgmath2.c: New test. 2007-07-11 Jakub Jelinek <jakub@redhat.com> [BZ #4776] * elf/dl-load.c (_dl_rtld_di_serinfo): Output / in LD_LIBRARY_PATH, RPATH etc. as "/" rather than "", don't segfault on empty paths, instead output ".". * dlfcn/Makefile (distribute): Add glreflib3.c. (module-names): Add glreflib3. ($(objpfx)tst-dlinfo.out): Depend on glreflib3.so rather than glreflib1.so. (LDFLAGS_glreflib3.so): New. * dlfcn/tst-dlinfo.c (do_test): Load glreflib3.so instead of glreflib1.so. * dlfcn/glreflib3.c: New file. * intl/finddomain.c (_nl_find_domain): If _nl_explode_name returned -1, return NULL. * intl/explodename.c (_nl_explode_name): Return -1 if _nl_normalize_codeset failed.
