I would like to make the following member of AsmPrinter be protected
void EmitInlineAsm(StringRef Str, const MDNode *LocMDNode = 0,
InlineAsm::AsmDialect AsmDialect =
InlineAsm::AD_ATT) const;
I have some stubs that I want to emit in MipsAsmParser .
Are there any objections to doing this?

Stubs to emit in MipsAsmPrinter
I think you were one of the people that was against me emitting the inline
asm earlier as part of the IR.
Well, now I am starting to move that to the back end of code generation due
to other issues that were not apparent when I first implemented this mips16
hard float.
Also, it was agreed at that time that it would be better if possible to do
things this way.

Why not just note that you need to emit the functions as you output
and then emit them during MC?

Let me go back one step...<br>
<br>
You are saying that instead of using EmitRawText, that I try and do
this with the higher level AsmPrinter methods.<br>
<br>
<i></i>Here is a little snipped that does not even include
instructions:<br>
<br>
OutStreamer.EmitRawText("\t.section\t.mips16.call.fp"+Twine(Symbol)+",\"ax\",@progbits");<br>
OutStreamer.EmitRawText(".align 2");<br>
OutStreamer.EmitRawText(".nomips16");<br>
OutStreamer.EmitRawText(".nomicromips");<br>
OutStreamer.EmitRawText("\t.ent\t__call_stub_fp_" +
Twine(Symbol));<br>
OutStreamer.EmitRawText("\t.type\t__call_stub_fp_" +
Twine(Symbol) + ", @function");<br>
OutStreamer.EmitRawText("\t__call_stub_fp_" + Twine(Symbol) +
":");<br>
OutStreamer.EmitRawText("\t.size __call_stub_fp_" +
Twine(Symbol) +<br>
", .-__call_stub_fp_" + Twine(Symbol));<br>
OutStreamer.EmitRawText("\t.end __call_stub_fp_" +
Twine(Symbol));<br>
<br>
(I have other code that generates the exact instructions).<br>
<br>
Here is the code it wants to generate:<br>
<br>
.globl __floatdidf<br>
# Stub function to call double __floatdidf ()<br>
.section .mips16.call.fp.__floatdidf,"ax",@progbits<br>
.align 2<br>
.set nomips16<br>
.set nomicromips<br>
.ent __call_stub_fp___floatdidf<br>
.type __call_stub_fp___floatdidf, @function<br>
__call_stub_fp___floatdidf:<br>
move $18,$31<br>
jal __floatdidf<br>
mfc1 $2,$f0<br>
mfc1 $3,$f1<br>
jr $18<br>
.size __call_stub_fp___floatdidf,
.-__call_stub_fp___floatdidf<br>
.end __call_stub_fp___floatdidf<br>
.globl __mips16_muldf3<br>
.globl __mips16_truncdfsf2<br>
<br>
<br>
This requires a lot of pseudo ops.<br>
