About
This CLI tool allows creating GNU ld linker script memory sections via command line.
Installation
cargo install ld-memory-cli
Usage
ld-memory is supposed to be hooked into your build system. Given the right arguments, it will output a snippet that can be used as part of a GNU ld linker script.
Example:
ld-memory --section rom:0x0:1024K
... outputs
_rom_start = 0x0;
_rom_length = 0x100000;
MEMORY
{
rom : ORIGIN = 0x0, LENGTH = 0x100000
}
An offset can be specified, which will be added to ORIGIN
and subtracted from
LENGTH
:
❯ ld-memory --section rom:0x0:1024K:128
_rom_start = 0x80;
_rom_length = 0xFFF80;
MEMORY
{
rom : ORIGIN = 0x80, LENGTH = 0xFFF80
}
Empty field counts as "0". Simple arithmetic is allowed.
❯ ld-memory --section rom:0x0:1024K:128 --section empty:: --section other:0x0+128K:1K+7K
_rom_start = 0x80;
_rom_length = 0xFFF80;
_empty_start = 0x0;
_empty_length = 0x0;
_other_start = 0x20000;
_other_length = 0x2000;
MEMORY
{
rom : ORIGIN = 0x80, LENGTH = 0xFFF80
empty : ORIGIN = 0x0, LENGTH = 0x0
other : ORIGIN = 0x20000, LENGTH = 0x2000
}
