- add VpiStub: fixed-layout blob written next to every .vpi (dual write at all
writers, Ensure() backfills a missing or stale companion on cache reuse)
- serve arity/signature queries for top-level functions from the blob, with a
silent fallback to the text scanner (methods, varargs, duplicates, corrupt file)
- prefer the injected declare over the text arity in the cross-module check
- CDefine/type text indexes and in-place SSA renumbering and bulk appends
- WIP: char* conversion in CallGenBase and CallGenLeafKit
--spend-file <path> instruments every compiled function with
vpf_enter(id, name) / vpf_leave(id); main additionally calls
vpf_install(path, level). includes/vprofile.vp keeps the tables (no
allocation on the hot path), times with QPC and writes the report from
atexit, so normal return and exit() both produce it.
--vpf 0 off | 1 call counts | 2 +per-function time (default) |
3 +caller/callee edges
*A report path is resolved against the output exe directory, so
../prof.txt and absolute paths behave as documented regardless of the
process cwd.
*Instrumented include objects use their own cache suffix
(.binary.vpf<N>, stacked with the asan/traceback suffixes) and that
cache is cleared once when profiling is enabled.
*StubMergerBuild force-adds the vprofile runtime to the reachable set;
FuncGenBase emits a declare on demand because the instrumented module
usually does not import vprofile.
*--repl is rejected: the fragment DLL is loaded at runtime and does not
link the runtime.
--build-self no longer keeps a whitelist: SelfBuild.CollectForwardedArgs
drops only --build-self / --project / --build-dir and forwards every
other argument verbatim, so a self-build can enable the same modes as a
normal build.
