Quoting Joel Sherrill <joel.sherr...@oarcorp.com>:
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 list archives and found none.
The arc-elf port in mainline gcc is for the architecture used by the ARCtangent-A4 and older cores, which has been superseded by the ARCompact architecture. The first article that a Google search turned up suggests that this was in 2001:
