Fix crash accessing builtins in sanitizer.def and after (PR jit/82174)
Calls to gcc_jit_context_get_builtin_function that accessed builtins
in sanitizer.def and after (or failed to match any builtin) led to
a crash accessing a NULL builtin name.
The entries with the NULL name came from these lines in sanitizer.def:
/* This has to come before all the sanitizer builtins. */
DEF_BUILTIN_STUB(BEGIN_SANITIZER_BUILTINS, (const char *)0)
[...snip...]
/* This has to come after all the sanitizer builtins. */
DEF_BUILTIN_STUB(END_SANITIZER_BUILTINS, (const char *)0)
This patch updates jit-builtins.c to cope with such entries, fixing the
crash.
gcc/jit/ChangeLog:
PR jit/82174
* jit-builtins.c (matches_builtin): Ignore entries with a NULL
name.
gcc/testsuite/ChangeLog:
PR jit/82174
* jit.dg/test-error-gcc_jit_context_get_builtin_function-unknown-builtin.c:
New test case.
