From 82d16b150ce3287f4e9f33e86bdde32bc455b193 Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Wed, 30 Dec 2020 15:51:10 -0800 Subject: memlayout: Store region sizes as separate symbols This patch changes the memlayout macro infrastructure so that the size of a region "xxx" (i.e. the distance between the symbols _xxx and _exxx) is stored in a separate _xxx_size symbol. This has the advantage that region sizes can be used inside static initializers, and also saves an extra subtraction at runtime. Since linker symbols can only be treated as addresses (not as raw integers) by C, retain the REGION_SIZE() accessor macro to hide the necessary typecast.
