Hi All,
Our project is - to optimize instruction scheduling in gcc, by
detecting structural hazards. We are looking at the dfa(deterministic finite
automaton) currently used by gcc to detect structural hazards. We have the
following doubts regarding the same:
1. The starting point of gener

Do you have an example of why this is so for your target?

genautomata is compiled into the build/genautomata binary in your build
tree. It is then invoked during t
--enable-plugin is used by classpath (part of libjava) and now by GCC itself.
disabling the build of the gcjwebplugin now disables plugin support in GCC as
well. Please could the option for enabling GCC plugin support be renamed to
something like --enable-plugins, --enable-gcc-plugin, --enable-g

Hi,
I got a random unsolicited email about arc-elf since
I pop up in google a lot asking cross compiler questions.
I decided to try to build it and as PR41747 indicates
4.3.4, 4.4.1, and the head all fail building libgcc2.c
in the same way. T
I did a search for arc-elf in the test results mail
