Are you are talking about the "Arm GNU Toolchain" heavily used by 
embedded developers, found here?

<https://developer.arm.com/Tools%20and%20Software/GNU%20Toolchain>

The page "Support and training" has the list of contact information, bug 
report systems, etc., for various parts of the toolchain.  Basically, 
ARM pay Linaro to handle the packaging and builds, so anything related 
to that gets reported to them.  The compiler, assembler, debugger and 
libraries are all taken directly from the open source projects.  So if 
there is an issue with the compiler itself, that is for GCC.  As always 
for these things, search the bug trackers and mailing list archives 
before filing any new issues.  And if you want to post on a GCC mailing 
list, the correct list is "gcc-help" for help with GCC (this list is for 
discussions about gcc development, rather than usage).

If you got the toolchain as part of a toolset, development kit, SDK or 
IDE from a microcontroller manufacturer, it can also help to report 
issues to them on their forums.  It is common that manufacturer's 
toolchains are slightly behind the latest versions from Arm's page, and 
Arm's builds are behind the mainline GCC development.  It does not help 
if you report bugs to GCC if the GCC developers have already fixed them 
- your aim instead is to bug the supplier into updating their tools.
