Can you change raw_fd_ostream::has_colors to memoize the result of FileDescriptorHasColors(FD) instead? That should give most of the performance gain without breaking the abstractions as much.

joerg added a comment to D85691: lld: link libatomic if needed for Timer.

This issue is on my long term TODO list. If there are no 64bit atomics, it is a really stupid idea to use them for timekeeping. I think for the use case of Timer, just splitting it into second and subsecond with explicit overflow handling is perfectly reasonable and does not affect the correctness of the normal use as the aggregates are only accessed on completion?

Please don't change the style of the code, it messes up review and the full source. Please split the introduction and testing of the new relocation into one patch and using a different set of relocations to implement large code model. The latter part needs at least a test as well?

joerg added a comment to D80300: [Driver] Add DEFAULT_DYLD_PREFIX and DEFAULT_RPATH to complement DEFAULT_SYSROOT.

I see that more as a short-coming in the existing DEFAULT_SYSROOT behavior and less an argument for making more cases like it. So the general idea is that for turnkey toolchains,
we want to allow customizing the "default" target of the toolchain to hard-code options like --sysroot, --target, -Wl,-rpath etc. Those are all related, so when using a different target, they no longer make sense. One way to deal with all those options in a consistent manner is hook into the logic for determining the current target, if none is explicitly specified on the command line or implicit from the executable name, then prepend some additional flags on the command line based on some cmake variable or so. This flags shouldn't trigger the unused argument warnings, so you can always pass -Wl,-rpath, --sysroot etc, independent of whether the compiler is in preprocessing / compile / assemble / link mode. That seems to be a more general and systematic approach than adding many additional build-time options.

I do agree with the feature request, but I'm not sure about the implementation. It doesn't seem to work well with the cross-compiling support in the driver as clearly shown by the amount of tests that need patching. Is cross-compiling a concern for you at all? Otherwise I would suggest going a slightly different route and use default values iff no "-target" or "target-command" mechanism is active. Might need a way to temporarily disable unused flag warnings, but that way would be pretty much toolchain independent?

joerg added a comment to D75799: [Intrinsic] Give "is.constant" the "convergent" attribute.

The original code has a functional dependency between sz and bytes and whether they can be constant evaluated. But the code doesn't express that. I don't think we can enforce that in any sensible way. There are valid use cases after all where partial inlining would result in entirely sensible decisions, just think about the more typical case of __builtin_constant_p selecting between inline asm taking immediate operands and one taking register/memory operands. That's why I am saying that I consider it a lot more useful to provide reliable building blocks to express the dependency and make sure they work.

Yes, builtin_expect is just noise here. The point I wanted to make is that both sz and bytes should be used in builtin_constant_p in the other condition.

joerg added a comment to D75799: [Intrinsic] Give "is.constant" the "convergent" attribute.

IMO the root of the problem here is that the branches are mixing predicated variables (bytes) with non-predicated variables (sz). If users want deterministic behavior here, that shouldn't be done.

joerg added a comment to D75799: [Intrinsic] Give "is.constant" the "convergent" attribute.

I was discussing this with Bill off-list to get a better idea of the original test case. Basically, with the new constant intrinsic pass, we can provide a stronger semantic: the default LLVM pass chain always constant folds expressions involving is.constant and performs DCE trivially dead branches resulting from the former folding. This means that if the original expression is adjusted from:

if (__builtin_expect(!!(sz >= 0 && sz < bytes), 0)) {
    if (!__builtin_constant_p(bytes))
    ...
}

to the functionally equivalent:

if (!(__builtin_constant_p(sz) && __builtin_constant_p(bytes) && sz >= 0 && sz >= bytes) && __builtin_expect(!!(sz >= 0 && sz < bytes), 0)) {
    if (!__builtin_constant_p(bytes))
    ...
}

then we can actually ensure proper DCE even with -O0 in the default pass chain. That depends over all on two properties:

  • If __builtin_constant_p is constant folded by clang, it must DCE the appropiate places.
  • the constant intrinsic pass is run

With -O1 or higher, this should work in general.

Adjust some tests to do minimal sanity checking of the alignment for C++03 only. Add an explicit check that __STDCPP_NEW_ALIGNMENT__ is more general than max_align_t if both are present.

It still seems to be a perfectly reasonable optimisation under the semantics of is.constant. The code here seems to be an abuse of it though and makes assumptions that are not sensible.

I'm confused by that example. If jumpthreading makes it possible to answer true, it is no differerent from inlining and other use cases. The reverse is the problematic case, turning constant cases into non-constant cases?

joerg added a comment to D73245: Avoid using std::max_align_t in pre-C++11 mode.

libc++ has no idea what a correct max_align_t is. The internal definition works due to historic requirements that all three fundamental types are supported for new/delete, but we don't have any such guarantees for every other context. A correctly implemented stddef.h does not provide max_align_t in C++03 mode, since that would pollute the global namespace. This means that libc++ currently has two failure modes: on NetBSD, it outright tries to use a non-existing symbol. On other platforms it silently defines max_align_t in a way that can be subtle wrong.

joerg added a comment to D73245: Avoid using std::max_align_t in pre-C++11 mode.

Let me clarify the situation for a moment:
(1) libc++ does try to work in C++03 mode. See the separate implementation of <functional> for pre-C++11. It is also desirable to support. This is completely beside the question of TR1 support.
(2) The only reason why max_align_t is currently necessary is because it is used as default alignment in <new>.
(3) Most compilers we care about already have a preprocessor symbol specifically for that purpose.

Can you declare a volatile variable and set that from f instead?

joerg updated the diff for D65280: Add a pass to lower is.constant and objectsize intrinsics.

Switch the pass to use two rounds. The first round will collect all relevant intrinsics in RPO, the second one will translate them accordingly.
