bin2c is used to create a valid C file out of a binary file where two symbols will be globally defined: <name> and <name>_size. <name> is passed as the first parameter of the host binary. Building using goto-cc reported that the purgatory binary code (the only current user of this utility) declares kexec_purgatory_size as 'size_t' where bin2c generate <name>_size to be 'int' so in a 64-bit host where sizeof(size_t) > sizeof(int) this type mismatch will always yield the wrong value for big-endian architectures while for little-endian it will be wrong if the object laid in memory directly after kexec_purgatory_size contains non-zero value at the time of reading. This commit changes <name>_size to be size_t instead. Note: Another way to fix the problem is to change the type of kexec_purgatory_size to be 'int' as there's this check in code: (kexec_purgatory_size <= 0) Signed-off-by: Michael Tautschnig <tautschn@amazon.com> Cc: Vivek Goyal <vgoyal@redhat.com> Acked-by: Dave Young <dyoung@redhat.com> Signed-off-by: Michal Marek <mmarek@suse.com> |
