2021-06-27Use XtUIntPtr for integer types that can hold pointersAlex Richardson
Various Xt*Id types are integer types that are used to hold pointers. Use uintptr_t for standards-compliant conversion and to support architectures where long cannot hold pointers (e.g. CHERI). I found these by compiling libXt with the CHERI Clang compiler, as it warns about conversions from integer to pointer that do not use intptr_t.

2021-06-27XtArgVal: Support architectures where pointers are bigger than longAlex Richardson
On CHERI-enabled architectures (e.g. Arm's Morello), pointers are twice the size of addresses (i.e. 128 bits for Morello, 64 bits for 32-bit RISC-V). However, XtArgVal is currently defined as long, so it cannot be used to store pointers on these architectures. This commit changes XtArgVal to use intptr_t instead, which should be long on most architectures but is larger for CHERI. It also introduces XtIntPtr/XtUIntPtr which will be used in follow-up changes. This commit should also help on LLP64 ABIs where long is 32 bits but pointers are 64 bits. I am not sure what the compiler and C standard requirements are, so I've guarded the use of stdint.h with `#if __STDC_VERSION__ >= 199901L`. I've also added a _Static_assert() when compiling in C11 mode to statically verify that the XtArgVal type requirements are met. Signed-off-by: Alex Richardson <Alexander.Richardson@cl.cam.ac.uk>
2021-06-16Define LONG64 if __SIZEOF_LONG__ indicates 64-bit longAlex Richardson
All modern compilers (GCC>=4.6, Clang>=3.0) define this macro, so we can use it to detect 64-bit longs without adding to the architecture list. This change is needed to successfully run xeyes on a FreeBSD CHERI-RISC-V QEMU VM via SSH forwarding.
