Several of the Q6INSN's in the imported directory have a ; after them - bleh.
Here's an example.
Q6INSN(L2_loadw_locked,"Rd32=memw_locked(Rs32)",
ATTRIBS(A_LOAD,A_RESTRICT_SLOT0ONLY), "Load word with lock",
{ fEA_REG(RsV); fLOAD_LOCKED(1,4,u,EA,RdV) });
So, if I do this, there are syntax errors.
const char * const opcode_syntax[XX_LAST_OPCODE] = {
#define Q6INSN(TAG, BEH, ATTRIBS, DESCR, SEM) \
[TAG] = BEH,
#define EXTINSN(TAG, BEH, ATTRIBS, DESCR, SEM) \
[TAG] = BEH,
#include "imported/allidefs.def"
#undef Q6INSN
#undef EXTINSN
};
I'll remove the extra ;'s from the imported files and make the change in this
file.
