主题: Re: [edk2-devel] [PATCH 1/1] BaseTools GenFw: Fix regression issue

convert the image to ACPI data

Hi Liming,

On Sat, Jun 05, 2021 at 09:18:54 +0800, gaoliming wrote:

With GCC49 tool chain, aslc file is compiled into elf image.
But, its text section has no CODE attribute. So, it can't be detected
by new GenFw tool.For this type file. its text section is not required.
Its data section will be converted to acpi table.

This fix is to remove assert check when the generated image is ACPI

Note - this does not only affect GCC49: it also affects at least
GCC5 and CLANG38. This patch resolves the issue.

Tested-by: Leif Lindholm <leif@...> (GCC49, GCC5, CLANG38)

Thanks!
