The compiler targeting armv6 (with -mcpu=3Dcortex_a7 specified) that reported this sugge= sted use of llabs (from C99). The labs parameter and return type need not match size_t well for the purpo= se, even ignoring unsigned vs. signed issue for the same width if that occurs. bytes_change =3D (size_t) llabs(newsize - oldsize); likely would be more auto adjusting without compiler warnings for current contexts. [Depends on what set_pkg_jobs_summary_pkg(. . ., &oldsize, &newsi= ze, . . .) is doing under the variations in types for various contexts. Likely oldsize and newsize values do track size_t or a signed variant with the same width to an extent.] If prior to C99 is to be covered (where llabs might not exist even if the t= ypes involved here do exist) then an explicit expansion of an expression (or mac= ros that expand to such) would be a way to get that more auto-adjusting nature: bytes_change =3D (size_t) ((oldsize <=3D newsize) ?newsize - oldsize :oldsize-newsize); --=20 You are receiving this mail because: You are the assignee for the bug.=
