PDB HashTable: Make iterator key type const

Having the hash table key change during iteration is bad, so make it
impossible. Nothing relied on the key type not being const.

(This is also necessary to be able to call the const version of
iterator_facade_base::operator->(). Nothing calls this, and nothing
will, but I tried using it locally during development and it took me a
while to understand what was going wrong.)

Also rename the iterator typedef to const_iterator.

No behavior change.

Original commit message:

ELF.h contains two getSymbol methods

One of these methods calls another, which in turn
contains untested error message which doesn't

5 years ago[ARM] MVE Vector Shifts
David Green [Mon, 15 Jul 2019 11:35:39 +0000 (11:35 +0000)]
[ARM] MVE Vector Shifts

This adds basic lowering for MVE shifts. There are many shifts in MVE, but the
instructions handled here are:
 VSHL (imm)
 VSHRu (imm)
 VSHRs (imm)
 VSHL (vector)
 VSHL (register)

MVE, like NEON before it, doesn't have shift right by a vector (or register).
We instead have to negate the amount and shift in the opposite direction. This
means we have to convert any SHR's into a form of SHL (that is still signed or
unsigned) with a negated condition and selecting from there. MVE still does
have shifting by an immediate for SHL, ASR and LSR.

This adds lowering for these and for register forms, which work well for shift
lefts but may require an extra fold of neg(vdup(x)) -> vdup(neg(x)) to potentially
work optimally for right shifts.

Summary:
SSE1 only supports v4f32. But does have instructions like movlps/movhps that load/store 64-bits of memory.

I'd like to maybe use this same thing for SSE2 and later as well, but that will need more work to be supported by EltsFromConsecutiveLoads to avoid regressing lit tests. I'd maybe also like to combine bitcasts with these load/stores nodes now that the types are disconnected. And I'd also like to consider canonicalizing (scalar_to_vector + load) to vzext_load.

If you want I can split the mechanical tablegen stuff where I added the 32/64 off from the sse1 change.

5 years ago[BitcodeReader] Use tighter upper bound to validate forward references.
Florian Hahn [Sun, 14 Jul 2019 12:35:50 +0000 (12:35 +0000)]
[BitcodeReader] Use tighter upper bound to validate forward references.

At the moment, bitcode files with invalid forward reference can easily
cause the bitcode reader to run out of memory, by creating a forward
reference with a very high index.

We can use the size of the bitcode file as an upper bound, because a
valid bitcode file can never contain more records. This should be
sufficient to fail early in most cases. The only exception is large
files with invalid forward references close to the file size.

There are a couple of clusterfuzz runs that fail with out-of-memory
because of very high forward references and they should be fixed by this
patch.

A concrete example for this is D64507, which causes out-of-memory on
systems with low memory, like the hexagon upstream bots.

[SystemZ] Fix addcarry of addcarry of const carry (PR42606)

This fixes https://bugs.llvm.org/show_bug.cgi?id=42606 by extending
D64213. Instead of only checking if the carry comes from a matching
operation, we now check the full chain of carries. Otherwise we might
custom lower the outermost addcarry, but then generically legalize
an inner addcarry.

Support for dumping current PrettyStackTrace on SIGINFO (Ctrl-T)

Support SIGINFO (and SIGUSR1 for POSIX purposes) to tell what
long-running jobs are doing, as inspired by BSD tools (including on
macOS), by dumping the current PrettyStackTrace.

This adds a new kind of signal handler for non-fatal "info" signals,
similar to the "interrupt" handler that already exists for SIGINT
(Ctrl-C). It then uses that handler to update a "generation count"
managed by the PrettyStackTrace infrastructure, which is then checked
whenever a PrettyStackTraceEntry is pushed or popped on each
thread. If the generation has changed---i.e. if the user has pressed
Ctrl-T---the stack trace is dumped, though unfortunately it can't
include the deepest entry because that one is currently being

[test/Object, obj2yaml] - Move test cases from test/Object and cleanup.

test/Object is not correct place to have tests that check obj2yaml
functionality, because we have test/tools/obj2yaml folder for that.

In this patch I merged a few test cases with their YAMLs from Inputs
folder, converted one of binary inputs and moved them to
tools/obj2yaml folder.

There are still another tests that might need the same, so it is initial step.

[tools] [llvm-nm] Default to reading from stdin not a.out

Summary: This moves away from defaulting to a.out and uses stdin only if stdin has a file redirected to it. This has been discussed on the llvm-dev mailing list [[ https://lists.llvm.org/pipermail/llvm-dev/2019-July/133642.html | here ]].
