However to + detect accidental truncation of meaningful values, we give an error if the + truncated portion isn't either all 0 or all 1 bits. However, this can + still give counterintuitive errors. For if the user is thinking in 2's + complement 32-bit arithmetic (which would be quite natural), then they'd + expect the expression (-0xffffffff-2) to evaluate to -1 (0xffffffff). + However in 64-bit it evaluates to 0xfffffffeffffffff which does truncate + to the expected value but trips this error message. - Also add a test for the new method. + Because of this reduce the error to only a warnings, with a somewhat more + helpful message. + + Fixes: https://github.com/dgibson/dtc/issues/74 - Signed-off-by: Luca Weiss - Message-Id: <20220419194537.63170-1-luca@z3ntu.xyz> - Reviewed-by: Simon Glass Signed-off-by: David Gibson Commands to generate update patches: -git format-patch ed310803ea893ed0a8bba9c4ff0d9eb0063a8bef -- libfdt/fdt_addresses.c libfdt/fdt.c libfdt/fdt_empty_tree.c libfdt/fdt.h libfdt/fdt_ro.c libfdt/fdt_rw.c libfdt/fdt_strerror.c libfdt/fdt_sw.c libfdt/fdt_wip.c libfdt/libfdt_env.h libfdt/libfdt.h libfdt/libfdt_internal.h libfdt/TODO +git format-patch 2cd89f862cdb04d91c5d59c5b39647f7d5d5b3b8 -- libfdt/fdt_addresses.c libfdt/fdt.c libfdt/fdt_empty_tree.c libfdt/fdt.h libfdt/fdt_ro.c libfdt/fdt_rw.c libfdt/fdt_strerror.c libfdt/fdt_sw.c libfdt/fdt_wip.c libfdt/libfdt_env.h libfdt/libfdt.h libfdt/libfdt_internal.h libfdt/TODO sed -i 's%/libfdt/fdt.h%/cpukit/include/fdt.h%g' 00* sed -i 's%/libfdt/libfdt.h%/cpukit/include/libfdt.h%g' 00* sed -i 's%/libfdt/libfdt_env.h%/cpukit/include/libfdt_env.h%g' 00* -- cgit v1.2.3
