Adds live start to var insts. * Liveness macros have initial output. * Looking at different initialization scenarios. * Some discussion around liveness. * WIP for working out liveness end. * WIP Updated liveness using use lists. * Is now adding liveness information * Some small fixes. * WIP around liveness. * Seems to output liveness correctly for current scenario. * Tidy up liveness code. * Update comment arounds liveness to current status. * Small fixes to liveness test. * Add support for call in liveness analysis. * Improve liveness example with array access. * Small updates to comments. * Disable liveness test because inconsistencies with output on CI system. * Fix some issues brought up in PR. * Rename liveness instructions. --- source/slang/slang.cpp | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'source/slang/slang.cpp') diff --git a/source/slang/slang.cpp b/source/slang/slang.cpp index 985599022..3a180027a 100644 --- a/source/slang/slang.cpp +++ b/source/slang/slang.cpp @@ -4159,6 +4159,18 @@ void EndToEndCompileRequest::setDumpIntermediates(int enable) } } +void EndToEndCompileRequest::setTrackLiveness(bool v) +{ + enableLivenessTracking = v; + + // Change all existing targets to use the new setting. + auto linkage = getLinkage(); + for (auto& target : linkage->targets) + { + target->setTrackLiveness(v); + } +} + void EndToEndCompileRequest::setDumpIntermediatePrefix(const char* prefix) { m_dumpIntermediatePrefix = prefix; -- cgit v1.2.3
