The iteration order for a SmallPtrSet is not deterministic,

4 years ago[ValueLattice] Steal bits from Tag to track range extensions (NFC).
Florian Hahn [Fri, 17 Apr 2020 14:30:00 +0000 (15:30 +0100)]
[ValueLattice] Steal bits from Tag to track range extensions (NFC).

Users of ValueLatticeElement currently have to ensure constant ranges
are not extended indefinitely. For example, in SCCP, mergeIn goes to
overdefined if a constantrange value is repeatedly merged with larger
constantranges. This is a simple form of widening.

In some cases, this leads to an unnecessary loss of information and
things can be improved by allowing a small number of extensions in the
hope that a fixed point is reached after a small number of steps.

To make better decisions about widening, it is helpful to keep track of
the number of range extensions. That state is tied directly to a
concrete ValueLatticeElement and some unused bits in the class can be
used. The current patch preserves the existing behavior by default:
CheckWiden defaults to false and if CheckWiden is true, a single change
to the range is allowed.

Follow-up patches will slightly increase the threshold for widening.

4 years agoImplement _ExtInt as an extended int type specifier.
Erich Keane [Tue, 24 Dec 2019 15:28:40 +0000 (07:28 -0800)]
Implement _ExtInt as an extended int type specifier.

Introduction/Motivation:
LLVM-IR supports integers of non-power-of-2 bitwidth, in the iN syntax.
Integers of non-power-of-two aren't particularly interesting or useful
on most hardware, so much so that no language in Clang has been
motivated to expose it before.

However, in the case of FPGA hardware normal integer types where the
full bitwidth isn't used, is extremely wasteful and has severe
performance/space concerns.  Because of this, Intel has introduced this
functionality in the High Level Synthesis compiler[0]
under the name "Arbitrary Precision Integer" (ap_int for short). This
has been extremely useful and effective for our users, permitting them
to optimize their storage and operation space on an architecture where
both can be extremely expensive.

We are proposing upstreaming a more palatable version of this to the
community, in the form of this proposal and accompanying patch.  We are
proposing the syntax _ExtInt(N).  We intend to propose this to the WG14
committee[1], and the underscore-capital seems like the active direction
for a WG14 paper's acceptance.  An alternative that Richard Smith
suggested on the initial review was __int(N), however we believe that
is much less acceptable by WG14.  We considered _Int, however _Int is
used as an identifier in libstdc++ and there is no good way to fall
back to an identifier (since _Int(5) is indistinguishable from an
unnamed initializer of a template type named _Int).

Fix opt-viewer tests failing after move from cgi.escape to html.escape

These two tests utilize pre-generated opt-viewer output to diff against
a run of opt-viewer over a known yaml file.

In commit 4b428e8f (D76126), the escape function used for rendering was changed
from cgi.escape to html.escape. This modification causes a behavioral
difference with regards to quote characters.

cgi will not escape quotes by default, but html will.

Therefore, these tests were failing because they expected the old behavior
of "string", but was instead seeing &quot;string&quot.

This solution modifies the known test outputs to use the escaped quotes
rather than not escaping quotes during rendering for no particular reason.

It is notable that when testing the optimization records generated by
LLVM, there was never quotes in the remarks I could find, specifically in
the Callee field where they exist in the pre-generated yaml for testing.

[X86][MC][NFC] Reduce the parameters of functions in X86MCCodeEmitter(Part II)

Summary:
We determine the REX prefix used by instruction in `determineREXPrefix`,
and this value is used in `emitMemModRMByte' and used as the return
value of `emitOpcodePrefix`.

Before this patch, REX was passed as reference to `emitPrefixImpl`, it
is strange and not necessary, e.g, we have to write
```
bool Rex = false;
emitPrefixImpl(CurOp, CurByte, Rex, MI, STI, OS);
```
in `emitPrefix` even if `Rex` will not be used.

So we let HasREX be the return value of `emitPrefixImpl`. The HasREX is passed
from `emitREXPrefix` to  `emitOpcodePrefix` and then to
`emitPrefixImpl`. This makes sense since REX is a kind of opcode prefix
and of course is a prefix.

This simplfifies the code in SDB to just handle a splat constant
address or a 2 operand GEP in the same BB. This removes the
need for "findValue" since the operands to the GEP are

this form. The pattern I'm using for scalarizing, a scalar GEP
followed by a GEP with an all zeroes index, seems to be subject
