 /* True if .gpword or .gpdword should be used for switch tables.

+   There are some problems with using these directives with the
+   native IRIX tools:
 
-#define TARGET_GPWORD (TARGET_ABICALLS && (!TARGET_NEWABI || TARGET_GAS))
+      - It has been reported that some versions of the native n32
+       assembler mishandle .gpword, complaining that symbols are
+       global when they are in fact local.
+
+      - The native assemblers don't understand .gpdword.
+
+      - Although GAS does understand .gpdword, the native linker
+       mishandles the relocations GAS generates (R_MIPS_GPREL32
+       followed by R_MIPS_64).
+
+   We therefore disable GP-relative switch tables for n32 and n64
+   on IRIX targets.  */
