Bug #: 14406
Summary: Support .progmem<N>.data sections to work with GCC's
PR49868
Product: binutils
Version: 2.23 (HEAD)
URL: http://gcc.gnu.org/PR49868
Status: NEW
Severity: enhancement
Priority: P2
Component: ld
AssignedTo: unassig...@sourceware.org
ReportedBy: g...@gcc.gnu.org
CC: eric.wedding...@atmel.com
Classification: Unclassified
Target: avr
GCC's named address spaces like __flash1 will locate data to input section
.progmem.data1, see section "Limitations and Caveats" in
http://gcc.gnu.org/onlinedocs/gcc/Named-Address-Spaces.html
The default linker script should support these sections so
that programmers can use the new address spaces and their
default sections without writing their own linker script files
that define .progmem<N>.data
Moreover, the default linker script should change
*(.progmem*)
to
*(.progmem)
*(.progmem.*)
If .text overlaps with .progmem1 and .progmem1 in non-empty,
the linker should stop with an error.
If .progmem1 is empty, everything is fine.
Similar for all the other .progmem<N> sections and combinations.
