This patch cures the testsuite failure of bfin/20090914-3.c, which currently FAILs on bfin-elf with "(test for excess errors)" due to: 20090914-3.c:3:1: warning: return type defaults to 'int' [-Wimplicit-int] which is obviously not what this code was intended to test. Fixed by turning the code into a function returning the final "fract32" result, as simply specifying an "int" return type for main, results in the entire function being optimized away, as the result is unused.
Checked-in as obvious. 2021-10-24 Roger Sayle <ro...@nextmovesoftware.com> gcc/testsuite/ChangeLog * gcc.target/bfin/20090914-3.c: Tweak test case. Roger --
