GNU GCC Support Cirrus Logic Maverick Crunch Optimisation

Armadillo-9 は封印したけど,少し出し遅れた関連ネタ.
[Armadillo-9 was sealed down.
But this topic is related it.]

Armadillo-9 に載っている Cirrus Logic EP9315は,
Maverick Crunch Co-Processor と言う FPU が付属している.
[Armadillo-9 is Cirrus Logic EP9315 CPU borad.
EP9315 has Maverick Crunch Co-Processor as FPU.]

で,ネタと言うのは,
GNU GCC に関するこのFPU 向けに最適化するオプションの
バグに関するお話.
[Then,
this topic is when building GNU GCC for
to optimise this FPU's option,
it happens some bugs.]

このバグレポートを出したDario Massarinさん,
以前 #gentoo-embedded で少し話した所,
彼は,GNU as でフルアセンブルな Maverick Crunch 用の
アプリを作る強者だった. :o
GNU GCC 4.0.x のドキュメントに EP93xx の最適化オプションを発見し,
早速チャレンジして,巧く行かずこのバグレポートを出したらしい.
[Dario Massarin reported this bug.
I have talked with him via IRC on #gentoo-embedded
about this FPU features.
I think he is nice guy because he had made an application
which coding completely GNU as for Maverrick Crunch. :o
He had found the optimisation options related this features
in GNU GCC 4.0.x documents,
and he had tried it, but it build failed.]

で,Richard Earnshawさんから
この御返事,対応が早ーい! :o
当の本人もこの驚き様. :P
[And then,
Richard Earnshaw replied.
Oh-ho, SO FAST! :o
Dario Massarin surprised.]

その後,
もう一個バグが出たみたいだけど,
巧く行ったのかな?
あとで訊いておこうっと. :)
[Later,
it seems new bug comes.
Now, didn't it works about this features?
I want to talk about this things if there is a next time. :)]
