* Revert [InlineCost] cleanup calculations of Cost and ThresholdJordan Rupprecht2019-07-031-3/+3
| | | | | | | | This reverts r364422 (git commit 1a3dc761860d620ac8ed7e32a4285952142f780b) The inlining cost calculation is incorrect, leading to stack overflow due to large stack frames from heavy inlining. llvm-svn: 365000
* [InlineCost] cleanup calculations of Cost and ThresholdFedor Sergeev2019-06-261-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: Doing better separation of Cost and Threshold. Cost counts the abstract complexity of live instructions, while Threshold is an upper bound of complexity that inlining is comfortable to pay. There are two parts: - huge 15K last-call-to-static bonus is no longer subtracted from Cost but rather is now added to Threshold. That makes much more sense, as the cost of inlining (Cost) is not changed by the fact that internal function is called once. It only changes the likelyhood of this inlining being profitable (Threshold). - bonus for calls proved-to-be-inlinable into callee is no longer subtracted from Cost but added to Threshold instead. While calculations are somewhat different, overall InlineResult should stay the same since Cost >= Threshold compares the same.

* Enrich inline messagesDavid Bolvansky2018-08-051-3/+4
| | | | | | | | | | | | | | | | | | | | | | Summary: This patch improves Inliner to provide causes/reasons for negative inline decisions. 1. It adds one new message field to InlineCost to report causes for Always and Never instances. All Never and Always instantiations must provide a simple message. 2. Several functions that used to return the inlining results as boolean are changed to return InlineResult which carries the cause for negative decision. 3. Changed remark priniting and debug output messages to provide the additional messages and related inline cost. 4. Adjusted tests for changed printing.

* [LTO] Allow pass remarks with hotness to be set when emitting to stderrTeresa Johnson2018-05-041-0/+10
| | | | | | | | | | | | | | | | | | | | | Summary: Set setDiagnosticsHotnessRequested before the early exit check for a diagnostic output file, so that pass remarks with hotness works when emitting pass remarks to stderr (e.g. via -pass-remarks=.). Also fix the llvm-lto2 diagnistic handler so that it only calls exit(1) when the diagnistic is an error type. Otherwise the new test invocation of llvm-lto2 with -pass-remarks causes it to fail. The new code is consistent with the diagnostic handler elsewhere (e.g. on the LLVMContext).

* llvm-lto2: Move the LTO::run() action behind a subcommand.Peter Collingbourne2017-04-111-1/+1
| | | | | | | | | | | | | Move LTO::run() to a "run" subcommand so that we can introduce new subcommands for testing different parts of the LTO implementation. This doesn't use llvm::cl subcommands because it doesn't appear to be currently possible to pass an argument not associated with a subcommand to a subcommand (e.g. -lto-use-new-pm, -mcpu=yonah).
