BIT_FIELD_REF considered harmful

Currently, when we see code that compares a bitfield to a constant, in some cases we will turn the bitfield from a COMPONENT_REF into a BIT_FIELD_REF. For example, this test case is based on PR 22563: struct s { int a : 3; }; struct s g; int foo () { g.a = 2; return g.a != 2; } In .003t.

Disabling pch checking?

gcc-4.1-rc1 seems nice so far - it's the first version of gcc that can beat gcc-2.95.3 on one particular app - but it seems to be slow at preprocessing C++ source. This matters quite a bit when running distcc. In fact, it seems to take three times as long to build large C++ apps as gcc-2.95.3 did.

So is it feasible that I can make executable to output gcda file to my Host PC via fputs or fwrite? Sure. The easiest way is to run the program under a functional simulator of the nios2, that can map system calls from the C library to I/O on the target board. The Altera people probably kno
