[ Upstream commit 02bc220dc6dc7c56edc4859bc5dd2c08b95d5fb5 ]
intptr_t and uintptr_t are not big enough types on 32-bit architectures when printing 64-bit values, resulting to the following incorrect diagnostic output:
# get_syscall_info.c:209:get_syscall_info:Expected exp_args[2] (3134324433) == info.entry.args[1] (3134324433)
Replace intptr_t and uintptr_t with intmax_t and uintmax_t, respectively. With this fix, the same test produces more usable diagnostic output:
# get_syscall_info.c:209:get_syscall_info:Expected exp_args[2] (3134324433) == info.entry.args[1] (18446744072548908753)
