[ARM] Incorrect relocation type for Thumb2 B<cond>.w The Thumb2 conditional branch B<cond>.W has a different encoding (T3) to the unconditional branch B.W (T4) as it needs to record <cond>. As the encoding is different the B<cond>.W is given a different relocation type. ELF for the ARM Architecture (Table-13) states that R_ARM_THM_JUMP19 should be used for B<cond>.W. At present the MC layer is using the R_ARM_THM_JUMP24 from B.W. This change makes B<cond>.W use R_ARM_THM_JUMP19 and alters the existing test that checks for R_ARM_THM_JUMP24 to expect R_ARM_THM_JUMP19. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@271997 91177308-0d34-0410-b5e6-96231b3b80d8 Peter Smith 3 years ago
