| * | common: ubsan: ignore shifting one into sign bit | Ahmad Fatoum | 2019-10-14 | 1 | -0/+20 |
| | | | | | | | | | | | | | | The __ubsan_handle_shift_out_of_bounds handler would be called for code shifting a one into the sign bit like (1 << 31), which is all too common in barebox. It's technically UB, but it's so prevalent that it's highly unlikely to be treated by a compiler as anything else than the standard-compliant (1U << 31). Check for this case here and ignore it selectively. Signed-off-by: Ahmad Fatoum <ahmad@a3f.at> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> | ||||
| * | common: add generic CONFIG_UBSAN plumbing | Ahmad Fatoum | 2019-09-09 | 1 | -0/+442 |
| -fsanitize=undefined allows compile-time instrumentation of code to detect some classes of runtime undefined behavior. In preparation for allowing arches to provide infrastructure in support of this feature, add some generic UBSAN options and associated plumbing. These are only shown in the debug menu when the arch selects the appropriate symbol. The option is named equally to their Linux counterparts.
