Subject: [PATCH] Fix: compile fails for x32 arch
|
|
|
|
It fails to compile for x32 arch:
|
|
|
|
| .../src/common/utils.c: Assembler messages:
|
|
| .../src/common/utils.c:1026: Error: register type mismatch for `bsr'
|
|
| .../src/common/utils.c:1028: Error: operand type mismatch for `movq'
|
|
|
|
Add macro check that not to define that fls_u64() for x32.
