Bug ID: 21824
Summary: MSP430 relative PC 10-bit optimisation
Product: binutils
Version: 2.30 (HEAD)
Status: UNCONFIRMED
Severity: enhancement
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: bengreen5mx at gmail dot com
Target Milestone: ---
Created attachment 10283

Patch for this small enhancement.
I noticed that the bfd library performs an optimisation for only
the MSP430X which is also applicable to the MSP430.
The fix is quite simple and I have attached it as a patch.
bfd: PC-relative jump for MSP430
bfd/
* elf32-msp430.c (msp430_elf_relax_section):
The MSP430 and MSP430X both support 10bit PC-relative jump.
Ref: SLAU144J.pdf section 3.4.3 Jumps.
Changed the condition that applies the optimisation.
