2021-06-21tests: Fix signedness comparisons warnings Andre Przywara
With -Wsign-compare, compilers warn about a mismatching signedness in comparisons in various files in the tests/ directory. For about half of the cases we can simply change the signed variable to be of an unsigned type, because they will never need to store negative values (which is the best fix of the problem). In the remaining cases we can cast the signed variable to an unsigned type, provided we know for sure it is not negative. We see two different scenarios here: - We either just explicitly checked for this variable to be positive (if (rc < 0) FAIL();), or - We rely on a function returning only positive values in the "length" pointer if the function returned successfully: which we just checked. At two occassions we compare with a constant "-1" (even though the variable is unsigned), so we just change this to ~0U to create an unsigned comparison value. Since this is about the tests, let's also add explicit tests for those values really not being negative. This fixes "make tests" (but not "make check" yet), when compiled with -Wsign-compare.

2017-03-06Fix assorted sparse warnings David Gibson
This fixes a great many sparse warnings on the fdt and libfdt sources. These are mostly due to incorrect mixing of endian annotated and native integer types. This includes fixing a couple of quasi-bugs where we had endian conversions the wrong way around (this will have the right effect in practice, but is certainly conceptually incorrect). This doesn't make the whole tree sparse clean: there are many warnings in bison and lex generated code, and there are a handful of other remaining warnings that are (for now) more trouble than they're worth to fix (and are not genuine bugs).

2013-01-06dtc/tests: don't include fdt.h prior to libfdt.h Kim Phillips
tests will need fdt type definitions provided in a subsequent patch to libfdt_env.h. Since libfdt.h includes libfdt_env.h in the right order anyway, just remove the fdt.h include. Signed-off-by: Kim Phillips <kim.phillips@freescale.com> Acked-by: David Gibson <david@gibson.dropbear.id.au>
2012-04-09dtc: Basic integer expressions Stephen Warren
Written by David Gibson <david@gibson.dropbear.id.au>. Additions by me: * Ported to ToT dtc. * Renamed cell to integer throughout. * Implemented value range checks. * Allow U/L/UL/LL/ULL suffix on literals. * Enabled the commented test. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
