Indu Bhagat	99fde044fc	libsframe: add symbol versioning Define an empty base version LIBSFRAME_0.0 and add all symbols to version LIBSFRAME_1.0. The previous release of libsframe (libsframe.so.0) did not have versioned symbols. Adding a libsframe.ver file so that future releases of the library (and its consumers) can manage the changes better. For Solaris ld, use -M mapfile command line option. libsframe does not restrict the set of exported symbols, so at this time there is no need to fall back on the libtool's -export-symbols option for platforms where some other linker (with a different command line option for symbol versioning) may be used. libsframe/ * Makefile.am: Use symbol versioning for libsframe. * Makefile.in: Regenerated. * configure: Check for Solaris ld. * configure.ac: Regenerated. * libsframe.ver: New file.	3 years ago
Indu Bhagat	b91671f3f9	libsframe: add library versioning lisbframe was first released with Bintuils 2.40. As the library evolves, some changes will break the ABI. Add library versioning for users to manage these changes. For the next release of the library (libsframe.so.1), incompatible ABI changes are planned. These will include: - Deprecation of some APIs, like sframe_get_funcdesc_with_addr (), and - Change in the contract of some APIs (e.g., return type, behavior). In libtool-version, set the current to 1 to prepare for the upcoming release. Reset revision and age to 0. Add libtool-version file to EXTRA_DIST. libsframe/ * Makefile.am: Use libtool versioning. * Makefile.in: Regenerated. * libtool-version: New file.	3 years ago
Indu Bhagat	e4d5d12940	libsframe: testsuite: add sframe_find_fre tests for pltN entries 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.	3 years ago
Indu Bhagat	6a99f006ec	libsframe: testsuite: add tests for sframe_get_funcdesc_with_addr API 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.	3 years ago
Indu Bhagat	efd3b63b68	libsframe: testsuite: add new tests for sframe_find_fre API 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.	3 years ago
Alan Modra	d87bef3a7b	Update year range in copyright notice of binutils files 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.	3 years ago

Weimin Pan	19e559f1c9	libsframe: add the SFrame library 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.
