Any code that I generate for the Sparc fails at assembly time using a
gas assembler built for the Sparc.
I get code like the following from the code generator:
.text
.align 16
.globl main
.type main, #function
main:
save -96, %o6, %o6
and get a syntax error on the save instruction.
I think sparc syntax should be:
.text
.align 16
.globl main
.type main, #function
main:
save %o6, -96, %o6
Is that correct? Should I file a bug report?

Should I file a bug report?save %o6, -96, %o6 is the usual syntax for Sparc assemblers. But this instruction is so fundamental nothing could ever have worked if it's broken, so there may be something deeper going on.

There is no current sparc maintainer, so feel free to change it if one way works better for you. -Chris
