Apparently, it is already supposed to have a value if it is defined; there's
a piece of code in varasm.c that looks like this:
#ifdef READONLY_DATA_SECTION
READONLY_DATA_SECTION ();
#endif
This means I can't implement that suggestion.
Here's the next version of the patch. I hope all the configurations are
changed correctly now, but I can only test ix86-linux (this is also the
reason why I didn't change configurations like freebsd-elf to use flag_pic
as the value, although this would probably work as well).
Bernd
* final.c: Define JUMP_TABLES_IN_TEXT_SECTION to a default value
of 0 if it isn't defined.
(shorten_branches, final_scan_insn): Test value
of JUMP_TABLES_IN_TEXT_SECTION instead of just testing whether it
is defined.
* arm/coff.h: Define JUMP_TABLES_IN_TEXT_SECTION to 1.
* arm/tcoff.h: Likewise.
* i386/386bsd.h: Likewise.
* i386/freebsd-elf.h: Likewise.
* i386/freebsd.h: Likewise.
* i386/netbsd.h: Likewise.
* i386/ptx4-i.h: Likewise.
* i386/sysv4.h: Likewise.
* pa/pa.h: Likewise.
* rs6000/linux.h: Likewise.
* rs6000/rs6000.h: Likewise.
* sh/sh.h: Likewise.
* sparc/sp64-elf.h: Likewise.
* v850/v850.h: Likewise.
* rs6000/sysv4.h: Define JUMP_TABLES_IN_TEXT_SECTION to 0.
* i386/linux.h: Define JUMP_TABLES_IN_TEXT_SECTION to (flag_pic).
