Re: GCC 8.4.0 fails to build on loongson

2021-07-19 Thread manphiz

I've recently upgraded to -current on loongson and retried building GCC
8.4.0 and unfortunately it failed with the same error.  Looks like Clang
miscompiles bootstrapping GCC on mips64el/loongson.  Should I report
this upstream?  Any tips (like system info or logs to include) on filing
the bug?

Thanks.

If you want better support in ports for this hardware, especially in
low-level things like gcc, you're going to need to do most of the work
yourself.


Hi Stuart,

Understood.  I'll try to provide as much info as needed for debugging.



At the bottom of your build log, it says

configure: error: cannot compute sizeof (double)
See `config.log' for more details.

There might possibly be something useful in that file (there will be
multiple config.log files in the build directory, look for the newest).

Maybe the fix will be something simple, maybe not.


Looks like it caused the compiler to ICE when configuring 
mips64el-unknown-openbsd6.9/libgcc.  I'm afraid it may be harder to fix. 
 The relevant logs look like below (full log attached):

I tried to recompile the conftest.c by adding "-v" to the compiler flag
