[PATCH 6.12 212/590] selftests: harness: fix printing of mismatch values in __EXPECT()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dmitry V. Levin <ldv@xxxxxxxxx>

[ 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)
