[clangd] Not collect include headers for dynamic index for now.
Summary:
The new behaviors introduced by this patch:
o When include collection is enabled, we always set IncludeHeader field in Symbol
even if it's the same as FileURI in decl.
o Disable include collection in FileIndex which is currently only used to build
dynamic index. We should revisit when we actually want to use FileIndex to global
index.
o Code-completion only uses IncludeHeader to insert headers but not FileURI in
CanonicalDeclaration. This ensures that inserted headers are always canonicalized.
Note that include insertion can still be triggered for symbols that are already
included if they are merged from dynamic index and static index, but we would
only use includes that are already canonicalized (e.g. from static index).
Reason for change:
Collecting header includes in dynamic index enables inserting includes for headers
that are not indexed but opened in the editor. Comparing to inserting includes for
symbols in global/static index, this is nice-to-have but would probably require
non-trivial amount of work to get right. For example:
o Currently it's not easy to fully support CanonicalIncludes in dynamic index, given the way
we run dynamic index.
o It's also harder to reason about the correctness of include canonicalization for dynamic index
(i.e. symbols in the current file/TU) than static index where symbols are collected
offline and sanity check is possible before shipping to production.
o We have less control/flexibility over symbol info in the dynamic index
(e.g. URIs, path normalization), which could be used to help make decision when inserting includes.
As header collection (especially canonicalization) is relatively new, and enabling
it for dynamic index would immediately affect current users with only dynamic
index support, I propose we disable it for dynamic index for now to avoid
compromising other hot features like code completion and only support it for
static index where include insertion would likely to bring more value.

/* size: 8, cachelines: 1, members: 2 */
/* last cacheline: 8 bytes */
};
-bash-4.2$
The reason is that BPF backend is not yet implemented in elfutils backend
https://github.com/threatstack/elfutils/tree/master/backends
and pahole depends on elfutils for dwarf parsing and resolving relocation.
More specifically, the unsupported relocation in .debug_info for type/member name
against symbol table caused the incorrect result above. The following is
the raw .rel.debug_info for the above example,
Hex dump of section '.rel.debug_info':

Based on "type", the proper value will be extracted from symbol table
and filled in .debug_info so later on .debug_info can be properly
resolved against debug strings.
There are two ways to fix this problem. One is to fix elfutils by adding
BPF support which is desirable. This could take a long time and won't work
with already deployed pahole. For a short term workaround, we can disable
dwarf cross-section relation which specifically avoids debug_info and
symbol table cross relocation. This should help any dwarf-related tool
which has not implement BPF specific relocations yet.
Now .rel.debug_info does not have any relocation for symbol table and
.debug_info itself contains necessary relocation information by itself.
Hex dump of section '.debug_info':
0x00000000
7b000000 04000000 00000801 00000000 {...............

00000000 00001000 00000200 00000000 ................
location 0xc has 0, 0x12 has 0x37, 0x1a has 0x3e in place which
will be used in relocation resolution. Here, the values of 0, 0x37 and 0x3e
are offset in .debug_str section.
Please note the difference between two above .debug_info dumps.
With the fix, pahole works properly with BPF backend:
-bash-4.2$ clang -O2 -g -target bpf -c test.c
-bash-4.2$ pahole test.o
struct test_t {
int a; /* 0 4 */
int b; /* 4 4 */

Resubmit r325107 (case folding DJB hash)
The issue was that the has function was generating different results depending
on the signedness of char on the host platform. This commit fixes the issue by
explicitly using an unsigned char type to prevent sign extension and
adds some extra tests.
The original commit message was:
This patch implements a variant of the DJB hash function which folds the
input according to the algorithm in the Dwarf 5 specification (Section
6.1.1.4.5), which in turn references the Unicode Standard (Section 5.18,
"Case Mappings").
To achieve this, I have added a llvm::sys::unicode::foldCharSimple
function, which performs this mapping. The implementation of this
function was generated from the CaseMatching.txt file from the Unicode
spec using a python script (which is also included in this patch). The
script tries to optimize the function by coalescing adjecant mappings
with the same shift and stride (terms I made up). Theoretically, it
could be made a bit smarter and merge adjecant blocks that were
interrupted by only one or two characters with exceptional mapping, but
this would save only a couple of branches, while it would greatly
complicate the implementation, so I deemed it was not worth it.
Since we assume that the vast majority of the input characters will be
US-ASCII, the folding hash function has a fast-path for handling these,
and only whips out the full decode+fold+encode logic if we encounter a
character outside of this range. It might be possible to implement the
folding directly on utf8 sequences, but this would also bring a lot of
complexity for the few cases where we will actually need to process
non-ascii characters.

These tests were using lldbutil.append_to_process_working_directory to

Technically, now the path returned by this function does not point to
the process working directory for local tests, but I think it makes

launching the process in the build directory (and I intend to change
this for the handful of inferiors that actually care about their PWD,
