On MIPS, PIC calls are indirect calls that need to be dispatched via an ABI
mandated register. At expansion time we load the symbol into a pseudo then
expand the call. There is a linker optimization that can turn these indirect
calls into direct calls under some circumstances. This can improve b

Hello all,
I am trying to port a 32bit arch in GCC 4.4.0. My target has support
for 1bit, 2bit shift and add operations. I tried to write patterns for
this , but gcc is not generating those. The following are the patterns
that i have written in md file:

With 4.4, IRA happens to reuse the same register for both pseudos, so
sched2 is hand tied and cannot schedule them back again for us.
I can imagine compiling other programs for which preserving the 4.3 allocation
will induce performance degradation du

I have a question about the check for -rdynamic in gcc/configure.
What we have in configure.ac is:
# Check -rdynamic
LDFLAGS="$LDFLAGS -rdynamic"
AC_MSG_CHECKING([for -rdynamic])
AC_TRY_LINK([],[return 0;],
[AC_MSG_RESULT([yes]); have_rdynamic=yes],
[AC_MSG_RESULT([no])])
