[PATCH v1 1/7] LoongArch Port: gcc

[Joseph Myers]

You have:

> +#define GLIBC_DYNAMIC_LINKER_LP64 "/lib64/ld.so.1"

See my comments on the glibc patch series 
<https://sourceware.org/pipermail/libc-alpha/2021-August/130298.html>.  
Specifically, the point that all new glibc ports should have unique 
per-ABI dynamic linker names for each ABI supported by the port, 
preferably referencing the architecture name somewhere in the dynamic 
linker name.  /lib64/ld.so.1 is a name that's already in use, so should 
not be used by any ABI of this new port.

> +      error ("%<-march=%s%> does not work on a cross compiler.",

Error messages should not end with '.'.

> +      error ("%<-mtune=%s%> does not work on a cross compiler.",

Likewise.

I didn't see any additions to contrib/config-list.mk anywhere in the patch 
series.  (See "Back End" in sourcebuild.texi for a list of places you may 
need to update as part of a GCC port, including config-list.mk.)

Please make sure the back end builds cleanly with current GCC mainline.  
This can be tested either with a native bootstrap, or by building a cross 
compiler, using a native compiler of the same GCC mainline version for the 
build and configuring using --enable-werror-always (that configure option 
has the effect of enabling -Werror in the same way that later bootstrap 
stages in a native bootstrap do).
