From 85ab981a8e4e1a7a078dbf553cb20cb2e58aeff9 Mon Sep 17 00:00:00 2001 From: Brooks Davis Date: Thu, 27 Nov 2025 14:54:56 +0000 Subject: [PATCH] sys/_types.h: define fallback __(u)intcap_t __intcap_t and __uintcap_t are new primative types in CHERI-aware ABIs that are used to define (u)intptr_t. To allow coexistance of integer pointers and hybrid code, define them to __(u)intptr_t when they are not otherwise available.
