2023-06-09	libsframe: testsuite: add sframe_find_fre tests for pltN entries	Indu Bhagat	1	-4/+38
	Add a new test plt-findfre-1 to ensure lookup of SFrame stack trace information for pltN entries is correct. In this test, a dummy SFrame FDE of type SFRAME_FDE_TYPE_PCMASK is created. The size of the 'function code block' covered by the SFrame FDE is equivalent to 5 pltN entries of 16 bytes each. The test first looks up SFrame FREs for some addresses in the first pltN entry, followed by lookups for some addresses in the fourth pltN entry. libsframe/ * Makefile.in: Regenerated. * testsuite/libsframe.find/find.exp: Add new test. * testsuite/libsframe.find/local.mk: Likewise. * testsuite/libsframe.find/plt-findfre-1.c: New test.
2023-05-17	libsframe: testsuite: add tests for sframe_get_funcdesc_with_addr API	Indu Bhagat	1	-4/+38
	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.
2023-05-17	libsframe: testsuite: add new tests for sframe_find_fre API	Indu Bhagat	1	-9/+54
	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.
2023-01-01	Update year range in copyright notice of binutils files	Alan Modra	1	-2/+2
	The newer update-copyright.py fixes file encoding too, removing cr/lf on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and embedded cr in binutils/testsuite/binutils-all/ar.exp string match.

2022-11-15	libsframe: add the SFrame library	Weimin Pan	1	-0/+1158
	libsframe is a library that allows you to: - decode a .sframe section - probe and inspect a .sframe section - encode (and eventually write) a .sframe section. This library is currently being used by the linker, readelf, objdump. This library will also be used by the SFrame unwinder which is still to be upstream'd. The file include/sframe-api.h defines the user-facing APIs for decoding, encoding and probing .sframe sections. A set of error codes together with their error message strings are also defined. Endian flipping is performed automatically at read and write time, if cross-endianness is detected.
