Stores information required to parse a TU using a (possibly stale) Baseline preamble.
Later on this information can be injected into the main file by updating compiler invocation with apply
. This injected section approximately reflects additions to the preamble in Modified contents, e.g. new include directives.

void clang::clangd::PreamblePatch::apply | ( | CompilerInvocation & | CI | ) | const |
Adjusts CI (which compiles the modified inputs) to be used with the baseline preamble.
This is done by inserting an artifical include to the CI
that contains new directives calculated in create.
Definition at line 509 of file Preamble.cpp.

Builds a patch that contains new PP directives introduced to the preamble section of Modified
compared to Baseline
.
FIXME: This only handles include directives, we should at least handle define/undef.

std::vector< Inclusion > clang::clangd::PreamblePatch::preambleIncludes | ( | ) | const |
Returns #include directives from the Modified
preamble that were resolved using the Baseline
preamble.
This covers the new locations of inclusions that were moved around, but not inclusions of new files. Those will be recorded when parsing the main file: the includes in the injected section will be resolved back to their spelled positions in the main file using the presumed-location mechanism.
