Summary: wrong "opcode is not supported on this processor"
error message on MIPS 4KSD.
Product: gcc
Version: 4.4.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: inline-asm
AssignedTo: [email protected]
ReportedBy: [email protected]
using inline-assembler the compiler report error that opcode is not supported
on this processor.
I use a processor MAXIM USIP400C with 4KSD core. The processor support
"SmartMIPS ASE Cryptography Support". In the command line options the
"-march=4ksd" is selected.
When I try to compile the next line:
asm("mtlhx t0");
the compiler report this error:
Error: opcode not supported on this processor: mips32r2 (mips32r2) `mtlhx t0'
When I compile this source code using old gcc compiler (3.4.4) the code is
compiled correctly and worked correctly.
-----------------
The used compiler is:
gcc version 4.4.1 (Sourcery G++ Lite 4.4-226)
