0f8f0c57ea Fixes the generation of dwarf line debug information for the msp430, even in the presence of function sections and linker garbage collection.
PR 17940
	* dwarf2dbg.c (out_header): When generating dwarf sections use
	real symbols not temps for the start and end symbols.
	* config/tc-msp430.h (TC_FORCE_RELOCATION_SUB_SAME): Also prevent
	adjustments to relocations in debug sections.
	(TC_LINKRELAX_FIXUP): Likewise.

	* elf32-msp430.c (msp430_elf_relax_delete_bytes): Adjust debug
	symbols at end of sections.  Adjust function sizes.

65d7bab591 This patch enhances the MSP430 port of GAS so that, if requested, it will
generate warning messages about an instruction that changes the interrupt
state not being followed by a NOP instruction.

	* config/msp430/msp430.c: Replace known mcu array with known
	msp430 ISA mcu name array.
	Accept any name for -mmcu option.
	Add -mz option to warn about missing NOP following an interrupt
	status change.
	(check_for_nop): New.
	(msp430_operands): Emit a warning, if requested, when an interrupt
	changing instruction is not followed by a NOP.
	* doc/c-msp430.c: Document -mz option.

	* gas/msp430/bad.d: Add -mz option.
	* gas/msp430/bad.s: Add more cases where warnings should be
	generated.
	* gas/msp430/bad.l: Add expected warning messages.

34b822e3bc Add .data and .bss refsym symbols
For each object, if it has a nonempty .data or .bss section,
emit a symbol that could cause the startup code to selectively
link in the code to initialize those sections.

* config/tc-msp430.c (msp430_section): Always flag data sections,
regardless of -md.
(msp430_frob_section): New.  Make sure all sections are noticed if
they have content.
