    • re PR target/57756 (Function target attribute is retaining state of previously seen function) · bf7b5747 
      PR target/57756

The root-cause of this PR is that global_options is not restored to
default before calling ix86_valid_target_attribute_tree and hence
target attributes are incorrectly processed sometimes.

This patch refactors code in i386.c in functions in the call-chain of 
ix86_valid_target_attribute_tree to use any gcc_options struct passed
as a parameter. It replaces existing code which always uses the
global_options struct.
