To: binutils; +Cc: Indu Bhagat
libsframe provides an API to find the FRE associated with a given PC in
the program. This patch adds a direct test of this API.
In this test, we create two dummy SFrame FDEs with 4 FREs each. Then we
test that sframe_find_fre () works for the first, second, third and the
last FRE from one of the FDEs. Such a test ensures better regression
testing for the sframe_find_fre () function which is going to be the
bread and butter of an SFrame based stack tracer.
libsframe/
* Makefile.in: Regenerated.
* testsuite/libsframe.find/find.exp: New test.
* testsuite/libsframe.find/findfre-1.c: New test.
* testsuite/libsframe.find/local.mk: Build new test.
* testsuite/local.mk: Include libsframe.find.

* [COMMITTED] libsframe: testsuite: add tests for sframe_get_funcdesc_with_addr API
2023-05-18 6:20 [COMMITTED] libsframe: testsuite: add new tests for sframe_find_fre API Indu Bhagat

From: Indu Bhagat @ 2023-05-18 6:20 UTC (permalink / raw)
To: binutils; +Cc: Indu Bhagat
sframe_get_funcdesc_with_addr API is currently used internally by the
sframe_find_fre ().
In this test, we create three dummy SFrame FDEs with 4 FREs each. Then,
we use few negative tests to lookup FREs with PCs not in the range of
PCs covered by the FDEs, ensuring graceful return from
sframe_get_funcdesc_with_addr in all cases. Some positive tests are
also added that exercise further scenarios as well.
libsframe/
* Makefile.in: Regenerated.
* testsuite/libsframe.find/find.exp: Include new test.
* testsuite/libsframe.find/findfunc-1.c: New Test.
* testsuite/libsframe.find/local.mk: Include new test.
