2010-04-27	Merge branch 'bg/compiler-suppress-result-ignored' into dev	Erlang/OTP
	* bg/compiler-suppress-result-ignored: compiler tests: Eliminate "result of expression is ignored" warnings Silence warnings for expressions that are assigned to "_" OTP-8602 bg/compiler-suppress-result-ignored It is now possible to suppress the warning in code such as "list_to_integer(S), ok" by assigning the ignored value "_" like this: "_ = list_to_integer(S), ok".
2010-04-15	Silence warnings for expressions that are assigned to "_"	Björn Gustavsson
	There is currently no zero-cost way to silence the warning "the result of the expression is ignored", which is issued for code such as: list_to_integer(S), ok Such code can be useful for assertions or input validation. Teach the compiler to silence the warning for expressions that are explicitly assigned to to the "_" variable, such as: _ = list_to_integer(S), ok Implement it by having the v3_core pass annotate calls in Core Erlang like this: let <_> = ( call 'erlang':'list_to_integer'(S) -\| ['result_not_wanted'] ) in 'ok' and modifiy sys_core_fold to suppress the warning for any call having the annotation. We deliberately do not make it possible to silence the warnings for expressions like: {build,an,unnecessary,term}, ok or is_list(L), ok because we don't know of any real-world scenarios in which that would be useful.
