This is the fix of the regression issue at c6b872c6. Based on ELF spec, readonly alloc section is .rodata section. It is requried. This fix is to add back original check logic for ELF section. Now, the readonly alloc section and execute alloc section are regarded as .text section. Signed-off-by: Liming Gao <[email protected]> Cc: Bob Feng <[email protected]> Cc: Ray Ni <[email protected]> --- With this fix, previous fix commit ec1cffd9 is not required. But, the checker added by commit ec1cffd9 is correct for ACPI data conversion. So, I don't plan to revert it.
