Hi Ayal, Thanks for the inputs, I will try this on GCC 4.0, which sounds quite interesting. regards, Vasanth On 6/15/05, Ayal Zaks <[EMAIL PROTECTED]> wrote: > > > > > > Vasanth <[EMAIL PROTECTED]> > > > I am using powerpc-eabi-gcc (3.4.1) an

Software pipelining capabilities

ttp://gcc.gnu.org/ml/gcc/2003-09/msg00954.html that seems relevant. Would GCC 4.x be a better version for my requirement? If not, any ideas would be greatly appreciated. thanks in advance, Vasanth

Recog - unrecognized insn when clobber present

I get an unrecognized insn error soon after. The only difference between 43 and 46 seems to be that 43 underwent a combination with 44 and is subregging 0, while 46 is subregging to byte 4. Taking away the clobber makes the insn match and the code to compile. Any ideas what/where I should start checking? Help is greatly appreciated.. thanks, Vasanth

Re: Validating a C++ back-end

. Can I just take all those "dg-do run" tests and run them on my target? I am just looking for basic testing since I am only in the initial stages, before I go onto those full blown conformance tests. thanks for the clarifications so far, Vasanth On 5/10/05, Nathan Sidwell <[EM

Question about GCC 3.4.1 -O2 Optimization bug (i386 and rs6000)

goes away when I compile at -O1. I can reproduce this error on gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-20) and powerpc-eabi-gcc 3.4.1. Any info will be appreciated, so that I can track this bug. thanks, Vasanth = "..When all are one and one is all, To be
