Zachary Turner [Mon, 19 Mar 2018 19:53:51 +0000 (19:53 +0000)]
Support embedding natvis files in PDBs.

Natvis is a debug language supported by Visual Studio for
specifying custom visualizers.  The /NATVIS option is an
undocumented link.exe flag which will take a .natvis file
and "inject" it into the PDB.  This way, you can ship the
debug visualizers for a program along with the PDB, which
is very useful for postmortem debugging.

This is implemented by adding a new "named stream" to the
PDB with a special name of /src/files/<natvis file name>
and simply copying the contents of the xml into this file.

Additionally, we need to emit a single stream named
/src/headerblock which contains a hash table of embedded
files to records describing them.

This patch adds this functionality, including the /NATVIS
option to lld-link.

was influencing the placement of an IMPLICIT_DEF which had a later

6 years agoChanged createTemporaryFile without FD to actually create a file.

Changed createTemporaryFile without FD to actually create a file.

Summary:
This commit changes semantics of createUniqueFile and
createTemporaryFile variants that do not return file descriptors.
Previously they only checked if files exist, therefore being subject
to race conditions. Now they will create an empty file to avoid them.

Functions that do not create a file are now called
getPotentiallyUniqueTempFileName and getPotentiallyUniqueFileName.

Andrea Di Biagio [Mon, 19 Mar 2018 13:23:07 +0000 (13:23 +0000)]
[llvm-mca] Add pipeline stall events.

This patch introduces a new class named HWStallEvent (see HWEventListener.h),
and updates the event listener interface. A HWStallEvent represents a pipeline
stall caused by the lack of hardware resources. Similarly to HWInstructionEvent,
the event type is an unsigned, and the exact meaning depends on the subtarget.
At the moment, HWStallEvent supports a few generic dispatch events.

The main goals of this patch is to remove the logic that counts dispatch stalls
from the DispatchUnit to the BackendStatistics view.

Previously, DispatchUnit was responsible for counting and classifying dispatch
stall events. With this patch, we delegate the task of counting and classifying
stall events to the listeners (i.e. in our case, it is view
"BackendStatistics"). So, the DispatchUnit doesn't have to do extra
(unnecessary) bookkeeping.

This patch also helps futher simplifying the Backend interface. Now class
BackendStatistics no longer has to query the Backend interface to obtain the
number of dispatch stalls. As a consequence, we can get rid of all the
'getNumXXX()' methods from class Backend.
The long term goal is to remove all the remaining dependencies between the
Backend and the BackendStatistics interface.

[TableGen] When trying to reuse a scheduler class for instructions from an InstRW, make sure we haven't already seen another InstRW containing this instruction on this CPU.

This is similar to the check later when we remap some of the instructions from one class to a new one. But if we reuse the class we don't get to do that check.

A lot of the violations are due to overlapping regular expressions, but that's not the only kind of issue it found.

towards fixing PR36662.

Internally, it tracks the number of available physical registers in each
register file (described by class RegisterFileInfo).

Each register file is associated to a list of MCRegisterClass indices. Knowing
the register class indices allows to map physical registers to register files.

The long term goal is to allow processor models to optionally specify how many
register files are implemented via tablegen.
