New Revision: 215127
URL: http://svn.freebsd.org/changeset/base/215127
Log:
Replace libgcc.a by libcompiler_rt.a.
libcompiler_rt.a is a BSD licensed C language runtime, which implements
many routines which are linked into binaries on architectures where
certain functionality is missing (e.g. 64 bits mul/div on i386).
Unfortunately, libcompiler_rt cannot replace libgcc entirely. Certain
features, such as an unwinder for exception handling, are missing.
That's why only libgcc.a is replaced for now, because this one does seem
to be complete.
Tested by: rene (amd64), nwhitehorn (powerpc), droso (i386 exprun)
and many others. Thanks!
