Mark C2x built-in functions as such.
Various built-in functions that GCC has as extensions are now standard
functions in C2x. This patch adds DEF_C2X_BUILTIN and uses it to mark
them as such. Some of the so-marked functions were previously
DEF_EXT_LIB_BUILTIN, while some DFP ones were DEF_GCC_BUILTIN
(i.e. __builtin_* only); both sets become DEF_C2X_BUILTIN. This in
turn requires flag_isoc2x to be defined in various front ends using
builtins.def.
As the semantics of the built-in functions should already be tested,
the tests added only verify that they are declared in C2x mode but not
in C11 mode. The test of DFP built-in functions being declared for
C2x goes in gcc.dg/dfp/, as while such built-in functions currently
don't depend on whether DFP is supported, that looks like a bug to me
(see bug 91985), so it seems best for the tests not to depend on
exactly how that bug might be fixed.
Bootstrapped with no regressions on x86_64-pc-linux-gnu.
gcc:
* builtins.def (DEF_C2X_BUILTIN): New macro.
(exp10, exp10f, exp10l, fabsd32, fabsd64, fabsd128, nand32)
(nand64, nand128, roundeven, roundevenf, roundevenl, strdup)
(strndup): Use DEF_C2X_BUILTIN.
* coretypes.h (enum function_class): Add function_c2x_misc.
gcc/ada:
* gcc-interface/utils.c (flag_isoc2x): New variable.
gcc/brig:
* brig-lang.c (flag_isoc2x): New variable.
gcc/lto:
* lto-lang.c (flag_isoc2x): New variable.
gcc/testsuite:
* gcc.dg/c11-builtins-1.c, gcc.dg/c2x-builtins-1.c,
gcc.dg/dfp/c2x-builtins-dfp-1.c: New tests.
