This happens because the "considered" facility assumed +that all targets would be visited on each walk through the dependency +graph: we used a bit for considered and toggled it on each pass; if +we didn't walk the entire graph on every pass the bit would get out +of sync. The new behavior after SV 44742 might return early without +walking the entire graph. To fix this I changed the considered value +to an integer which is monotonically increasing: it is then never +possible to incorrectly determine that a previous pass through the +graph already considered the current target. + +* filedef.h (struct file): make CONSIDERED an unsigned int. +* main.c (main): No longer need to reset CONSIDERED. +* remake.c (update_goal_chain): increment CONSIDERED rather than +inverting it between 0<->1. +(update_file_1): Reset CONSIDERED to 0 so it's re-considered. +(check_dep): Ditto. +* tests/scripts/features/double_colon: Add a regression test. +--- +diff --git a/filedef.h b/filedef.h +index 507a027..14b4187 100644 +--- a/filedef.h ++++ b/filedef.h +@@ -58,6 +58,8 @@ struct file + FILE_TIMESTAMP last_mtime; /* File's modtime, if already known. */ + FILE_TIMESTAMP mtime_before_update; /* File's modtime before any updating + has been performed. */ ++ unsigned int considered; /* equal to 'considered' if file has been ++ considered on current scan of goal chain */ + int command_flags; /* Flags OR'd in for cmds; see commands.h. */ + enum update_status /* Status of the last attempt to update. */ + { +@@ -96,8 +98,6 @@ struct file + unsigned int ignore_vpath:1;/* Nonzero if we threw out VPATH name. */ + unsigned int pat_searched:1;/* Nonzero if we already searched for + pattern-specific variables. */ +- unsigned int considered:1; /* equal to 'considered' if file has been +- considered on current scan of goal chain */ + unsigned int no_diag:1; /* True if the file failed to update and no + diagnostics has been issued (dontcare). */ + }; +diff --git a/main.c b/main.c +index 576f2e9..e606488 100644 +--- a/main.c ++++ b/main.c +@@ -2262,10 +2262,6 @@ main (int argc, char **argv, char **envp) + + for (i = 0, d = read_files; d != 0; ++i, d = d->next) + { +- /* Reset the considered flag; we may need to look at the file +- again to print an error. */ +- d->file->considered = 0; +- + if (d->file->updated) + { + /* This makefile was updated. */ +diff --git a/remake.c b/remake.c +index df1a9e0..5d5d67a 100644 +--- a/remake.c ++++ b/remake.c +@@ -57,8 +57,9 @@ unsigned int commands_started = 0; + static struct goaldep *goal_list; + static struct dep *goal_dep; + +-/* Current value for pruning the scan of the goal chain (toggle 0/1). */ +-static unsigned int considered; ++/* Current value for pruning the scan of the goal chain. ++ All files start with considered == 0. */ ++static unsigned int considered = 0; + + static enum update_status update_file (struct file *file, unsigned int depth); + static enum update_status update_file_1 (struct file *file, unsigned int depth); +@@ -90,12 +91,12 @@ update_goal_chain (struct goaldep *goaldeps) + + goal_list = rebuilding_makefiles ? goaldeps : NULL; + +- /* All files start with the considered bit 0, so the global value is 1. */ +- considered = 1; +- + #define MTIME(file) (rebuilding_makefiles ? file_mtime_no_search (file) \ + : file_mtime (file)) + ++ /* Start a fresh batch of consideration. */ ++ ++considered; ++ + /* Update all the goals until they are all finished. */ + + while (goals != 0) +@@ -247,10 +248,10 @@ update_goal_chain (struct goaldep *goaldeps) + } + } + +- /* If we reached the end of the dependency graph toggle the considered +- flag for the next pass. */ ++ /* If we reached the end of the dependency graph update CONSIDERED ++ for the next pass. */ + if (g == 0) +- considered = !considered; ++ ++considered; + } + + if (rebuilding_makefiles) +@@ -615,8 +616,8 @@ update_file_1 (struct file *file, unsigned int depth) + break; + + if (!running) +- /* The prereq is considered changed if the timestamp has changed while +- it was built, OR it doesn't exist. */ ++ /* The prereq is considered changed if the timestamp has changed ++ while it was built, OR it doesn't exist. */ + d->changed = ((file_mtime (d->file) != mtime) + || (mtime == NONEXISTENT_MTIME)); + +@@ -650,7 +651,7 @@ update_file_1 (struct file *file, unsigned int depth) + /* We may have already considered this file, when we didn't know + we'd need to update it.
