Hi ports --
So in my attempt to have once again a fully working Webkit for Loongson,
I have run into a snag. I have two patches at the bottom of this email
that, when applied, will allow webkit-1.6.3 to build and run on loongson.
So far with these patches:
*The SunSpider benchmark runs and completes.
*On webkit-gtk3-1.6.3, the Google search as you type feature works.
*Some JavaScript works.
However, a lot of JavaScript does not work and crashes webkit and the
browser. I've discovered that the quickest way to get a crash is to go
to gmail.com and attempt to log in.
Here are two gdb backtraces from logging into gmail.com (both with the
gtk2 version of webkit), the first compiled normally as per the
Makefile, the second compiled with -O0:
http://devio.us/~bcallah/gdb-surf.txt
http://devio.us/~bcallah/gdb-webkit.txt
I was hoping that someone could look through this and see what I've
missed, and hopefully get webkit fully working once again. If there's
something else you'd like me to include, please let me know.
Everything is being compiled on a Yeeloong, running -current with a
GENERIC kernel.
The "ideal" solution to this issue would be to enable the JIT on
Loongson, but our assembler is missing the .reloc pseudo-op, which is
necessary to compile the JIT for MIPS.
Thanks.
