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.
* 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
