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.
