Bug ID: 28217
Summary: Syntax error when memory region contains a hyphen
Product: binutils
Version: 2.37
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: sebastiaan.de.schaetzen at gmail dot com
Target Milestone: ---
I've recently upgraded from binutils 2.36.1 to version 2.37.
This has now caused some of the firmware code I'm working on to no
longer compile.
The firmware uses RIOT OS, and its linker script uses minus ("-")
symbols in some of its region names.
(specifically, it has a region called "bkup-ram" allowing one to store
data in special backup memory if the
microcontroller has it).
While this used to work, it now throws a syntax error
/usr/lib/gcc/arm-none-eabi/11.2.0/../../../../arm-none-eabi/bin/ld:cortexm_base.ld:215:
warning: memory region `bkup' not declared
/usr/lib/gcc/arm-none-eabi/11.2.0/../../../../arm-none-eabi/bin/ld:cortexm_base.ld:215:
syntax error
collect2: error: ld returned 1 exit status
Some of the relevant lines in cortexm_base.ld:
40 /* not all Cortex-M platforms use cortexm.ld yet */
41 MEMORY
42 {
43 bkup-ram (w!rx) : ORIGIN = _backup_ram_start_addr, LENGTH
= _backup_ram_len
44 }
208 _sbackup_data_load = LOADADDR(.backup.data);
209 .backup.data : ALIGN(4) {
210 _sbackup_data = .;
211 *(.backup.data)
212 _ebackup_data = .;
213 /* Round size so that we can use 4 byte copy in init */
214 . = ALIGN(4);
215 } > bkup-ram AT> rom
Renaming bkup-ram to bkup_ram fixes the issue.
Is this a regression in 2.37, or was it a bug that 2.36.1 even
accepted it in the first place?
