Hi
This patch allows to run pretty printer tests in _GLIBCXX_DEBUG
mode. If accepted we could even integrate the pretty printers tests
within the check-debug target like it is done for the check target.

I noticed that the latest GCC 9 snapshot actually identifies itself
as GCC 10 since it's been carved from trunk, not the release branch.

Hi Jeff,
Yes. The latter one "[PATCH] improve ifcvt optimization (PR
rtl-optimization/89430)" supersedes the earlier one " Fixing ifcvt issue as
exposed by BZ89430".

For now, gcc can not fold code like:
const char a[5] = "123"
__builtin_memchr (a, '7', sizeof a)
It tries to avoid folding out of string length although length of a is 5.
This is a bit conservative, it's safe to folding memchr/bcmp/memcmp

According to gnu document of function attributes, neither weakref nor

could be attached to a function defined in current translation unit.
Although GCC checks the attributes under some circumstances, it still

Hi,
GCC revision 267634 implemented two_value_replacement function.
However, a typo occurred during the parameter check, which caused
us to miss some optimizations.
The intent of the code might be to check that the input parameters
are const int and their difference is one. However, when I read
28 matches
