They're not needed for correctness. Add the correct memory barriers to the gcc legacy __sync built-in functions for atomic memory access. From the gcc documentation: In most cases, these built-in functions are considered a full barrier. That is, no memory operand is moved across the operation, either forward or backward. Further, instructions are issued as necessary to prevent the processor from speculating loads across the operation and from queuing stores after the operation. type __sync_lock_test_and_set (type *ptr, type value, ...) This built-in function is not a full barrier, but rather an acquire barrier. This means that references after the operation cannot move to (or be speculated to) before the operation, but previous memory stores may not be globally visible yet, and previous memory loads may not yet be satisfied. void __sync_lock_release (type *ptr, ...) This built-in function is not a full barrier, but rather a release barrier. This means that all previous memory stores are globally visible, and all previous memory loads have been satisfied, but following memory reads are not prevented from being speculated to before the barrier.

CVS commit: src/usr.bin/make/unit-tests

Committed By: rillig

Modified Files:
src/usr.bin/make/unit-tests: cond-cmp-numeric.exp cond-cmp-numeric.mk
Log Message:
tests/make: test spaces around numbers in comparisons
Just to see whether it is possible to write a conditional in the form
${ ${A} < ${B} :? ${A} : ${B} }, that is, with leading and trailing
whitespace, to make it easier for humans to read the code.
It's not possible, the result of this computation cannot be used in
further numeric comparisons, at least not in .if directives. Leading
space would work, but trailing space wouldn't.
On the other hand, they would work in expressions of the form
${ ${A} < ${B} :? ... : ... } since in these, the condition is first
expanded and then parsed. But that is an implementation detail that is
not documented and it is also difficult to understand.
