GAS: Replace macro LITERAL_PREFIXDOLLAR_HEX with a runtime value.
In an upcoming commit, I need to be able to set the prefix used to introduce hexadecimal literal constants using a command line flag. This is not currently possible, because the switch which determines this (LITERAL_PREFIXDOLLAR_HEX) is a macro set at build time. This change substitutes it for a variable to be set at start up. gas/ChangeLog: * expr.c (literal_prefix_dollar_hex): New variable. (operand)[case '$']: Use the new variable instead of the old macro. Also, move this instance of "case '$'" next to the other one, and enable it only in the complementary proprocessor case. * expr.h (literal_prefix_dollar_hex): Declare it. * config/tc-epiphany.c (md_begin): Assign literal_prefix_dollar_hex. * config/tc-ip2k.c: ditto * config/tc-mt.c: ditto * config/tc-epiphany.h (LITERAL_PREFIXDOLLAR_HEX): Remove macro definition. * config/tc-ip2k.h: ditto * config/tc-mt.h: ditto
