gas PR gas/18581 * expr.c (get_symbol_end): Rename to get_symbol_name. Add a return parameter pointing to the start of the symbol. Allow symbol names enclosed in double quotes. (restore_line_pointer): New function. Replace the NUL character inserted into the input stream with the given character. If the character was a double quote, advance the input pointer. * expr.h (get_symbol_end): Delete. (get_symbol_name): Add prototype. (restore_line_pointer): Prototype. * read.h (SKIP_WHITESPACE_AFTER_NAME): New macro. * doc/as.texinfo (Symbol Intro): Document that symbol names can now be enclosed in double quotes. * cond.c (s_ifdef): Replace get_symbol_end with get_symbol_name.

2005-10-11This adjusts equate handling byNick Clifton1-2/+13
- allowing true forward references (which will always assume the referenced symbols have at the point of use) through the new .eqv pseudo-op and the new == operator - disallowing changing .equiv-generated equates (so that the protection this provides is both forward and backward) - snapshotting equates when their value gets changed so that previous uses don't get affected by the new value. - allowing expressions in places where absolute expressions (or register names) are needed which were not completely resolvable at the point of their definition but which are fully resolvable at the point of use In addition it fixes PR/288.
