A newer version of V8 seems to crash my compiler. Using GCC 3.3.3 in src/codegen-ia32.cc line 4383:
Old V8 code: < // Seed the result with the formal parameters count, which will be < // used in case no arguments adaptor frame is found below the < // current frame. < __ Set(eax, Immediate(Smi::FromInt(scope_->num_parameters()))); < New V8 code.....this code crashes the compiler. --- > // ArgumentsAccessStub takes the parameter count as an input argument > // in register eax. Create a constant result for it. > Result count(Handle<Smi>(Smi::FromInt(scope_->num_parameters())), this); On Mar 31, 12:41 pm, Kasper Lund <[email protected]> wrote: > On Tue, Mar 31, 2009 at 7:30 PM, MJ <[email protected]> wrote: > > Yes, I am using --trace_calls.
