+ * generic/tclDTrace.d (new file): add DTrace provider for Tcl; allows
+ * generic/tclCompile.h: tracing of proc and command entry &
+ * generic/tclBasic.c: return, bytecode execution, object
+ * generic/tclExecute.c: allocation and more; with essentially
+ * generic/tclInt.h: zero cost when tracing is inactive;
+ * generic/tclObj.c: enable with --enable-dtrace configure
+ * generic/tclProc.c: arg (disabled by default, will only
+ * unix/Makefile.in: enable if DTrace is present).
+ * unix/configure.in: [Patch 1793984]
+
+ * macosx/GNUmakefile: enable DTrace support.
+ * macosx/Tcl-Common.xcconfig:
+ * macosx/Tcl.xcodeproj/project.pbxproj:
+
+ * generic/tclCmdIL.c: factor our core of InfoFrameCmd() into internal
+ TclInfoFrame() for use by DTrace probes.
+
+ * unix/configure: autoconf-2.59
+ * unix/tclConfig.h.in: autoheader-2.59
