[BPF] Remove relocation for patchable externs · d46a6a9e

Yonghong Song authored Oct 10, 2019

Previously, patchable extern relocations are introduced to patch
external variables used for multi versioning in
compile once, run everywhere use case. The load instruction
will be converted into a move with an patchable immediate
which can be changed by bpf loader on the host.

The kernel verifier has evolved and is able to load
and propagate constant values, so compiler relocation
becomes unnecessary. This patch removed codes related to this.

In openFileForRead don't cache erroneous entries if the error relates to them... · 4abac533

Kousik Kumar authored Oct 10, 2019

In openFileForRead don't cache erroneous entries if the error relates to them being directories. Add tests.

Summary:
It seems that when the CachingFileSystem is first given a file to open that is actually a directory, it incorrectly
caches that path to be errenous and throws an error when subsequently a directory open call is made for the same
path.
This change makes it so that we do NOT cache a path if it turns out we asked for a file when its a directory.

[MCA] Show aggregate over Average Wait times for the whole snippet (PR43219) · a5e65c1c

Roman Lebedev authored Oct 10, 2019

Summary:
As disscused in https://bugs.llvm.org/show_bug.cgi?id=43219,
i believe it may be somewhat useful to show //some// aggregates
over all the sea of statistics provided.

Example:
```
Average Wait times (based on the timeline view):
[0]: Executions
[1]: Average time spent waiting in a scheduler's queue
[2]: Average time spent waiting in a scheduler's queue while ready
[3]: Average time elapsed from WB until retire stage

      [0]    [1]    [2]    [3]
0.     3     1.0    1.0    4.7       vmulps     %xmm0, %xmm1, %xmm2
1.     3     2.7    0.0    2.3       vhaddps    %xmm2, %xmm2, %xmm3
2.     3     6.0    0.0    0.0       vhaddps    %xmm3, %xmm3, %xmm4
       3     3.2    0.3    2.3       <total>
```
I.e. we average the averages.

[lldb] Add log output for the support files we pass to the CppModuleConfiguration · ccd54a13

CppModuleConfiguration is the most likely point of failure when we have weird

to figure out why we can't find a valid configuration as the configuration only
depends on the list of file paths.

To solve this issue the tests are updated to use the new
`--ignore-case` option of FileCheck.

Fix the unwinding plan augmentation from x86 assembly · 50703223

Pavel Labath authored Oct 10, 2019

Unwind plan augmentation should compute the plan row at offset x from
the instruction before offset x, but currently we compute it from the
instruction at offset x. Note that this behavior is a regression
introduced when moving the x86 assembly inspection engine to its own
file
(https://github.com/llvm/llvm-project/commit/1c9858b298d79ce82c45a2954096718b39550109#diff-375a2be066db6f34bb9a71442c9b71fcL913);
the original version handled this properly by copying the previous
instruction out before advancing the instruction pointer.

MinidumpYAML: Add support for the memory info list stream · 3aa7e766

Pavel Labath authored Oct 10, 2019

Summary:
The implementation is fairly straight-forward and uses the same patterns
as the existing streams. The yaml form does not attempt to preserve the
data in the "gaps" that can be created by setting a larger-than-required
header or entry size in the stream header, because the existing consumer
(lldb) does not make use of the information in the gap in any way, and
attempting to preserve that would make the implementation more
complicated.

This test was previously passing because myabs was actually emitted into the

use the libc++ directory structure (the /v1/ directory was just called /include/).

This patch gives myabs a default argument which we can't get from debug information
and inlines the function to make sure we can't call it from LLDB without loading
the C++ module.
