Subject: [PATCH 23/25] PowerPC: Mark RTTI typeid tests as expected fail before
|
||
|
|
inferior start
|
||
|
|
|
||
|
|
On PowerPC targets, the RTTI typeinfo objects for base types may not
|
||
|
|
be emitted until the inferior has been started. As a result,
|
||
|
|
the `gdb.cp/typeid.exp` test fails when checking typeid results
|
||
|
|
before program execution begins.
|
||
|
|
|
||
|
|
This patch marks these specific cases as expected failures on PowerPC
|
||
|
|
when the inferior has not yet started, aligning the behavior with other
|
||
|
|
targets (such as Clang) where RTTI emission is deferred until runtime.
|
||
|
|
|
||
|
|
gdb/testsuite/
|
||
|
|
* gdb.cp/typeid.exp (do_typeid_tests): Mark PowerPC pre-start
|
||
|
|
RTTI typeinfo checks as expected failures for `i`, `cp`, and `ccp`.
