-/* This pass serves two closely-related purposes:
-
- 1. It conditionally executes calls that set errno if (a) the result of
- the call is unused and (b) a simple range check on the arguments can
- detect most cases where errno does not need to be set.
-
- This is the "conditional dead-code elimination" that gave the pass
- its original name, since the call is dead for most argument values.
- The calls for which it helps are usually part of the C++ abstraction
- penalty exposed after inlining.
-
- 2. It looks for calls to built-in functions that set errno and whose
- result is used. It checks whether there is an associated internal
- function that doesn't set errno and whether the target supports
- that internal function. If so, the pass uses the internal function
- to compute the result of the built-in function but still arranges
- for errno to be set when necessary. There are two ways of setting
- errno:
-
- a. by protecting the original call with the same argument checks as (1)
-
- b. by protecting the original call with a check that the result
- of the internal function is not equal to itself (i.e. is NaN).
-
- (b) requires that NaNs are the only erroneous results. It is not
- appropriate for functions like log, which returns ERANGE for zero
- arguments. (b) is also likely to perform worse than (a) because it
- requires the result to be calculated first. The pass therefore uses
- (a) when it can and uses (b) as a fallback.
-
- For (b) the pass can replace the original call with a call to
- IFN_SET_EDOM, if the target supports direct assignments to errno.
-
- In both cases, arguments that require errno to be set should occur
- rarely in practice. Checks of the errno result should also be rare,
- but the compiler would need powerful interprocedural analysis to
- prove that errno is not checked. It's much easier to add argument
- checks or result checks instead.
-
- An example of (1) is:
-
- log (x); // Mostly dead call
- ==>
- if (__builtin_islessequal (x, 0))
- log (x);
-
- With this change, call to log (x) is effectively eliminated, as
- in the majority of the cases, log won't be called with x out of
- range. The branch is totally predictable, so the branch cost
- is low.
-
- An example of (2) is:
-
- y = sqrt (x);
- ==>
- if (__builtin_isless (x, 0))
- y = sqrt (x);
- else
- y = IFN_SQRT (x);
- In the vast majority of cases we should then never need to call sqrt.
-
- Note that library functions are not supposed to clear errno to zero without
- error. See IEEE Std 1003.1, section 2.3 Error Numbers, and section 7.5:3 of
- ISO/IEC 9899 (C99).
-
- The condition wrapping the builtin call is conservatively set to avoid too
- aggressive (wrong) shrink wrapping. */
