The last argument of an FP-classify function was checked for vailidity
as an expression, but we never ensured that the usual unary
conversions/etc properly resulted in a valid value. Thus, when we got
the value, it was null, so we had a null dereference.
This patch instead fails out/marks the function call as invalid if the
argument is incorrect. I DID consider just allowing it to continue, but
the result was an extraneous error about how the last argument wasn't a
float (in this case, it was an overload set).
Fixes: #107411
A significant number of our tests in C accidentally use functions
without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,
void func();
becomes
void func(void);
This is the second batch of tests being updated (there are a significant
number of other tests left to be updated).
- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).
