Use functions with prototypes when appropriate; NFC

2022-02-15T14:28:02+00:00

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 tenth batch of tests being updated (there are a
significant number of other tests left to be updated).

When a variable has a specified asm name, but isn't using the register storage class, the asm name doesn't specify a register. PR12244.

Add support for passing variables declared to use a xmm register to asm

2011-01-02T03:59:13+00:00

statements using the "x" constraint.

llvm-svn: 122679

Add support for declaring register contraints in variables. They are only used

2010-12-30T22:59:32+00:00

in asm statements:

register int foo asm("rdi");

asm("..." : ... "r" (foo) ...

We also only accept these variables if the constraint in the asm statement is "r".

This fixes most of PR3933.
