From 750115a65c4f4aab1818ae01a841c04ba589dc1d Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Fri, 5 Apr 2013 12:36:00 +0000 Subject: [PATCH] toolchain/uClibc: Disable mips16 for uClibc for now For now, build uclibc without -mips16. There's no mips16 syscall support AFAIK and uclibc uses inline assembly syscalls a lot. In addition, touching errno means touching a TLS model symbol, and that's not supported in gcc 4.6. The __set_errno macro can be put back to calling errno_location(). This allows much of the library to be built in mips16 mode. I don't understand the implications to the thread library of doing this. A list of "build as -mno-mips16" C source files can be placed in the mips architecture-dependent build files. Maintaining the list would be no fun.
