[gdb] Fix cc-with-dwz regression I noticed a regression with board cc-with-dwz: ... FAIL: gdb.cp/m-static.exp: static const int initialized elsewhere FAIL: gdb.cp/m-static.exp: info variable everywhere ... The problem started with commit 0494dbecdf "Consolidate partial symtab dependency reading". The commit replaces the dwarf2_psymtab::expand_psymtab specific reading of dependencies, which contains a "dependencies[i]->user == NULL" test, with a generic partial_symtab::read_dependencies call, which does not test the user field. This patch fixes the regression by adding back the test, in the generic partial_symtab::read_dependencies. Build and reg-tested on x86_64-linux. Tested natively, as well as with boards cc-with-dwz and cc-with-dwz-m. The patch fixes all 33 regressions with cc-with-dwz, and all 2929 regression with cc-with-dwz-m. gdb/ChangeLog: 2020-02-21 Tom de Vries PR gdb/25534 * psymtab.c (partial_symtab::read_dependencies): Don't read dependency if dependencies[i]->user != NULL. --- gdb/psymtab.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/gdb/psymtab.c b/gdb/psymtab.c index 56576b3bce..fd7fc8feff 100644 --- a/gdb/psymtab.c +++ b/gdb/psymtab.c @@ -1688,7 +1688,8 @@ partial_symtab::read_dependencies (struct objfile *objfile) { for (int i = 0; i < number_of_dependencies; ++i) { - if (!dependencies[i]->readin_p ()) + if (!dependencies[i]->readin_p () + && dependencies[i]->user == NULL) { /* Inform about additional files to be read in. */ if (info_verbose)
