Justin Bogner [Tue, 8 Mar 2016 00:39:51 +0000 (00:39 +0000)]
SelectionDAG: Store SDNode operands in an ArrayRecycler

Currently some SDNode operands are malloc'd, some are stored inline in
subclasses of SDNode, and some are thrown into a BumpPtrAllocator.
This scheme is complex, inconsistent, and makes refactoring SDNodes
fairly difficult.

Instead, we can allocate all of the operands using an ArrayRecycler
that wraps a BumpPtrAllocator. This keeps the cache locality when
iterating operands, improves locality when iterating SDNodes without
looking at operands, and vastly simplifies the ownership semantics.

It also means we stop overallocating SDNodes by 2-3x and will make it
simpler to fix the rampant undefined behaviour we have in how we
mutate SDNodes from one kind to another (See llvm.org/pr26808).

This is NFC other than the changes in memory behaviour, and I ran some
LNT tests to make sure this didn't hurt compile time. Not many tests
changed: there were a couple of 1-2% regressions reported, but there
were more improvements (of up to 4%) than regressions.

[ScopedNoAliasAA] Make test basic.ll less confusing

Summary:
This testcase had me confused.  It made me believe that you can use
alias scopes and alias scopes list interchangeably with alias.scope and
noalias.  Both langref and the other testcase use scope lists so I went
looking.

Turns out using scope directly only happens to work by chance.  When
ScopedNoAliasAAResult::mayAliasInScopes traverses this as a scope list:

!1 = !{!1, !0, !"some scope"}

, the first entry is in fact a scope but only because the scope is
happened to be defined self-referentially to make it unique globally.

The remaining elements in the tuple (!0, !"some scope") are considered
as scopes but AliasScopeNode::getDomain will just bail on those without
any error.

This change avoids this ambiguity in the test but I've also been
wondering if we should issue some sort of a diagnostics.

8 years ago[MS ABI] Mangle symbols names longer than 4096 characters correctly
David Majnemer [Mon, 7 Mar 2016 08:51:17 +0000 (08:51 +0000)]
[MS ABI] Mangle symbols names longer than 4096 characters correctly

Really long symbols are hashed using MD5 and prefixed/suffixed with the
usual sigils.  There is an additional reason beyond the usual
compatibility with MSVC, it is important to keep COFF symbols shorter
than 0xFFFF because the CodeView debugging format has a maximum
symbol/record size of 0xFFFF.

There are some quirks worth noting:
- Some mangled names reference other entities which are mangled
separately.  A quick example:

int I;
template <int *> struct S {};
S<I> s;

In this case, the mangling for 's' doesn't depend directly on the
mangling for 'I'.  While 's' would need an MD5 hash if 'I' also needed
one, the hash for 's' applied to the fully realized mangled name.  In
other words, the mangled name for 's' will not depend on the MD5 of the
mangled name for 'I'.

- Some mangled names, like the venerable CatchableType, embed the MD5
verbatim.

- Finally, the complete object locator is handled as a special case.
A complete object locators are mangled exactly like a VFTable except for
a small deviation in the prefix sigils.  However, complete object
locators for hashed vftables result in a complete object locator whose
name is identical to the vftable except for an additional suffix.
