Subject: [gdb/testsuite] Ignore pass in gdb_caching_proc
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9db2b96b0759fda3347743caba66a395d115e335;p=binutils-gdb.git

[gdb/testsuite] Ignore pass in gdb_caching_proc

Before commit d4295de4f3 "[gdb/testsuite] Handle missing gnatmake in
gnat_runtime_has_debug_info", calling the gdb_caching_proc
gnat_runtime_has_debug_info could generate a pass because of using
gdb_compile_ada.

This has been fixed in that commit by using a factored out variant
gdb_compile_ada_1, which does not call pass.

Additionally, fix cases like this in more generic way: by ignoring pass calls
during execution of a gdb_caching_proc.

Build and reg-tested on x86_64-linux.

gdb/testsuite/ChangeLog:
