[llvm-commits] [patch] Fix ARM varg functions with 5 or more regular arguments

[Rafael Espindola]

The attached patch fixes functions like

void f (int a1, int a2, int a3, int a4, int a5,...)

In ARMTargetLowering::LowerFormalArguments if the function has 4 or
more regular arguments we correctly don't save the r0-r3 registers on
the stack. The problem is that we also set VarArgsFrameIndex using an
offset of 0, which is only correct if the function has exactly 4
regular arguments.

Is the patch OK with a testcase? I promises to write one before committing :-)

Cheers,
