Re: [C++ Patch] PR 71105 ("lambdas with default captures improperly have function pointer conversions")

OK for trunk and 6. The regression is from another issue; this bug just prevents a simple workaround for that bug. Jason

Re: libiberty: Don't needlessly clear xmemdup allocated memory

Alan Modra writes: > * xmemdup.c (xmemdup): Use xmalloc rather than xcalloc. In glibc at least, calloc can be faster than memset if the kernel is pre-zero-ing pages. Thus, in those cases, your change makes the code slower by adding an unneeded memset. Have you considered these cases?

[C++ Patch] PR 71105 ("lambdas with default captures improperly have function pointer conversions")

Hi, I think submitter is right that by the grammar even an alone capture-default counts as a lambda-capture, thus a conversion function to pointer to function should not be added. I don't see how this issue may count as a regression, but, assuming the analysis is correct, the fix should be sa

[PATCH] match.pd: optimize unsigned mul overflow check

Hello, For unsigned A, B, 'A > -1 / B' is a nice predicate for checking whether 'A*B' overflows (or 'B && A > -1 / B' if B may be zero). Let's optimize it to an invocation of __builtin_mul_overflow to avoid the divide operation. The following patch implements that as a match.pd transformation.

[v3 PATCH] Protect allocator-overloads of tuple-from-tuple constructors from cases that would create dangling references.

The fix to avoid binding dangling references to temporaries for tuple's constructors that take tuples of different type didn't include the fix for allocator overloads. That was just lazy, and I should feel ashamed. This patch fixes it, and takes us one step further to pass libc++'s testsuite for tu

Do not predict one edge by the same path based predictor multiple times
