Subject: Patch for arm-none-linux-gnueabi build failure
This patch fixes another piece of bug 24998, fallout from adding
__floatun*. Unlike the problems with missing functions, this is one
with duplicate functions: builds for arm-none-linux-gnueabi fail
because __floatundisf and __floatundidf are multiply defined, once in
libgcc2.c and once in ieee754-[ds]f.S. Where a target defines its own
version of a function in libgcc2.c, it needs to be listed in
LIB1ASMFUNCS to avoid the libgcc2.c version being compiled. (In this
case, a group of functions are all included in the same object file so
inclusion in LIB1ASMFUNCS wasn't needed for the ARM version to get
compiled in the first place.)
Tested with cross-compiler to arm-none-linux-gnueabi; it fixes the
build of the compiler. OK to commit?
