[cmake] GetSVN.cmake takes a list of arguments

Summary:
GetSVN.cmake currently takes one or two pairs of <source directory path,
name>, then attempts to get the remote repository URL and source control
revision of the repositories at those one or two paths.

It takes two pairs in order for Clang to get the revision of both
itself, and its dependency LLVM.

For projects that rely upon both LLVM and Clang (Apple's Swift is one
example, but there are others), GetSVN.cmake is used to fetch *three*
revisions: Swift, Clang, and LLVM.

To support this use case, change GetSVN.cmake: instead of taking one or
two pairs (specified via `FIRST_SOURCE_DIR`/`FIRST_NAME`, have it take a list
of pairs (`SOURCE_DIRS`/`NAMES`).

In order to allow Clang to migrate, have GetSVN.cmake support both sets
of arguments for now. The old arguments can be removed once Clang begins
using the new arguments, and Swift can follow when it updates its
copy of LLVM.

Test Plan:
1. Perform a clean build of Clang, verify that `clang --version` still
   prints the correct LLVM and Clang revision information.
2. Modify Clang's CMake to use the new arguments, then perform another
   clean build. `clang --version` should still print the correct
   revision information.

[SimplifyCFG] Defer folding unconditional branches to LateSimplifyCFG if it can destroy canonical loop structure.

Summary:
When simplifying unconditional branches from empty blocks, we pre-test if the
BB belongs to a set of loop headers and keep the block to prevent passes from
destroying canonical loop structure. However, the current algorithm fails if
the destination of the branch is a loop header. Especially when such a loop's
latch block is folded into loop header it results in additional backedges and
LoopSimplify turns it into a nested loop which prevent later optimizations
from being applied (e.g., loop  unrolling and loop interleaving).

This patch augments the existing algorithm by further checking if the
destination of the branch belongs to a set of loop headers and defer
eliminating it if yes to LateSimplifyCFG.

[LV] Test once if vector trip count is zero, instead of twice

Generate a single test to decide if there are enough iterations to jump to the
vectorized loop, or else go to the scalar remainder loop. This test compares the
Scalar Trip Count: if STC < VF * UF go to the scalar loop. If
requiresScalarEpilogue() holds, at-least one iteration must remain scalar; the
rest can be used to form vector iterations. So in this case the test checks
instead if (STC - 1) < VF * UF by comparing STC <= VF * UF, and going to the
scalar loop if so. Otherwise the vector loop is entered for at-least one vector
iteration.

This test covers the case where incrementing the backedge-taken count will
overflow leading to an incorrect trip count of zero. In this (rare) case we will
also avoid the vector loop and jump to the scalar loop.

This patch simplifies the existing tests and effectively removes the basic-block
originally named "min.iters.checked", leaving the single test in block
"vector.ph".

[PM/LCG] Follow-up fix to r308088 to handle deletion of library
functions.

In the prior commit, we provide ordering to the LCG between functions
and library function definitions that they might begin to call through
transformations. But we still would delete these library functions from
the call graph if they became dead during inlining.

While this immediately crashed, it also exposed a loss of information.
We shouldn't remove definitions of library functions that can still
usefully participate in the LCG-powered CGSCC optimization process. If
new call edges are formed, we want to have definitions to be called.

We can still remove these functions if truly dead using global-dce, etc,
but removing them during the CGSCC walk is premature.

This fixes a crash in the new PM when optimizing some unusual libraries
that end up with "internal" lib functions such as the code in the "R"
language's libraries.

Object: preserve more information about DEF file

Preserve the actual library name as provided by the user.  This is
required to properly replicate link's behaviour about the module import
name handling.  This requires an associated change to lld for updating
the tests for the proper behaviour for the import library module name
handling in various cases.

Associated tests will be part of the lld change.

[scan-build-py] Patch to fix "-analyzer-config" option

I noticed that when I use "-analyze-config" option in scan-build-py, it
behaves differently from original perl based scan-build.

For example, command:

$ scan-build -analyzer-config ipa=basic-inlining make

Will work without any issues on perl version of scan-build. But on
scan-build-py it will throw an error message "error reading
'ipa=basic-inlining'".

After debugging, it turns out that the scan-build-py does not put
"-analyzer-config" flag in front of the analyzer config flags (in this
case is the "ipa=basic-inlining") in the final clang command line. This
patch fixes this issue.

5 years agoDebug Info: Add a file: field to DIImportedEntity.

Debug Info: Add a file: field to DIImportedEntity.

DIImportedEntity has a line number, but not a file field. To determine
the decl_line/decl_file we combine the line number from the
DIImportedEntity with the file from the DIImportedEntity's scope. This
does not work correctly when the parent scope is a DINamespace or a
DIModule, both of which do not have a source file.

This patch adds a file field to DIImportedEntity to unambiguously
identify the source location of the using/import declaration.  Most
testcase updates are mechanical, the interesting one is the removal of
the FIXME in test/DebugInfo/Generic/namespace.ll.

This fixes PR33822. See https://bugs.llvm.org/show_bug.cgi?id=33822
