I've simply checked my test results against a run-of-the-mill installation
|
|
on a redhat linux system for differences...
|
|
|
|
Here are the differences:
|
|
-----------------------------------------------------------
|

FAIL: gcc.c-torture/execute/ieee/rbug.c execution, -O0

This is the test summary:

Here is the corresponding test under gcc 2.8.1 (the actual numbers differ as
|
|
gcc does not support -Os)
|
|
|
|
=== gcc Summary ===
|
|
|

There is one bug in gcc 2.8.1 that also shows up in egcs under standard
|
|
OpenBSD configuration: if using -finline-functions, gcc emits stabs lines
|
|
for CTORS at an incorrect position. Hence, the linker no longer finds the
|
|
CTORS, hence everything breaks down. This has been reported to egcs-bugs.
|
|
|
|
The way we get around this problem is by relying on collect2: egcs is
|
|
built with use_collect2=yes, so it does no longer relies on stabs for
|
|
propert CTOR collection, and the bug is no longer visible.
