MSP430: Fix relocation overflow when using #lo(EXP) macro
gas/ChangeLog: 2020-01-15 Jozef Lawrynowicz <jozef.l@mittosystems.com> * config/tc-msp430.c (CHECK_RELOC_MSP430): Always generate 430X relocations when the target is 430X, except when extracting part of an expression. (msp430_srcoperand): Adjust comment. Initialize the expp member of the msp430_operand_s struct as appropriate. (msp430_dstoperand): Likewise. * testsuite/gas/msp430/msp430.exp: Run new test. * testsuite/gas/msp430/reloc-lo-430x.d: New test. * testsuite/gas/msp430/reloc-lo-430x.s: New test. include/ChangeLog: 2020-01-15 Jozef Lawrynowicz <jozef.l@mittosystems.com> * opcode/msp430.h (enum msp430_expp_e): New. (struct msp430_operand_s): Add expp member to struct. ld/ChangeLog: 2020-01-15 Jozef Lawrynowicz <jozef.l@mittosystems.com> * testsuite/ld-msp430-elf/msp430-elf.exp: Run new test. * testsuite/ld-msp430-elf/reloc-lo-430x.s: New test.
