[Bug c/25314] [3.4/4.0/4.1/4.2 Regression] Unreachable code at beginning of switch statement is not reported anymore
--- Comment #6 from Uwe dot Seimet at seimet dot de 2005-12-12 06:21 --- Subject: Re: [3.4/4.0/4.1/4.2 Regression] Unreachable code at beginning of switch statement is not reported anymore Hello, Another comment from my side: When using -Wunreachable-code as a means to detect unreachable code in a switch statement I noticed that, just like the manpage says, -Wunreachable-code issues a lot of warnings when compiling with -g. There are so many warnings with "-g -Wunreachable-code" that it is impossible to see which warning is justified and which is not. The behavior with old versions of gcc was much more transparent. With gcc 3.3 I got an accurate warning for the unreachable code in the code sample I sent you. Which gcc 4.0 I only get this warning with -Wunreachable-code, but there are so many other (not useful) warnings that -Wunreachable-code is not a good solution wrt the switch statement.

This is due to ADJUST_FIELD_ALIGN returning the wrong value for struct {double

[Bug c++/25355] New: reinterpret_cast<> yields different (and incorrect) results when using -O2
The test case:
#include
using namespace std;
int main()
{
unsigned int test = 1067320345;
cout << reinterpret_cast(test) << endl;
cout << "reinterpret_cast(test): " <<
reinterpret_cast(test) << endl;
}
When compiled using -g or -O1, the correct output is produced:
1.2345
reinterpret_cast(test): 1.2345
When compiled using -O2, the first reinterpret_cast<> produces incorrect
results. The actual value produced depends on the OS:
-NaN
reinterpret_cast(test): 1.2345
I tested this on Solaris 8 and on Linux Redhat WS3, with identical results. My
conclusion is that we're looking at an optimizer bug.

[Bug testsuite/25352] New: xfail within dg-do command has no effect
If you use an xfail command within a dg-do, it has no effect. E.g this generic
testcase will FAIL rather than XFAIL:
/* { dg-do preprocess { xfail *-*-* } } */
#error intentional failure!
int main(void)
{
return 0;
}
Right now, none of the ~100 testcases in the testsuite using this idiom are
honoring it. So they're either now passing or unnecessarily cluttering up
testsuite results.

[Bug libfortran/25340] Runtime error: "Read past ENDFILE record"
--- Comment #2 from fxcoudert at gcc dot gnu dot org 2005-12-11 10:52
---
So, following Steven's question on c.l.f, this code is illegal.
Most compilers report an EOF error (including Intel and g77), and branch if an
END tag is present. I think the error issued by gfortran currently is better
("Read past ENDFILE record"), ie more precise.
If people provide an END tag in the I/O statement, what do we want to do? I am
in favour of throwing an error, and not branching silently. I know (from c.l.f)
Brook thinks the same. I think we can close this as INVALID if you agree,
Steven.
