The -fallow-half-arguments-and-returns option was removed in
59528e4bdb27ed4ab3, replaced with an always-on target option under
AArch64/Arm. There are two tests - fp16-sema.c and renderscripts.rs that
test that an error is produced for __fp16 function args/returns, which
are now expected to pass for Arm/AArch64. i.e they no longer give the
same error as before on native Arm/AArch64 machines. Alter the targets
of those tests to compensate.
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).
Summary:
Create a new Frontend LangOpt to specify the renderscript language. It
is enabled by the "-x renderscript" option from the driver.
Add a "kernel" function attribute only for RenderScript (an "ignored
attribute" warning is generated otherwise).
Make the NativeHalfType and NativeHalfArgsAndReturns LangOpts be implied
by the RenderScript LangOpt.
