I agree edk2 firmware to support old EFI image. And, I review the change in BasePeCoffLib. But, I think it is unnecessary. Below is the current logic. On the first loop, DebugEntry.Type is EFI_IMAGE_DEBUG_TYPE_CODEVIEW, then will return. It doesn't enter into second loop. For mtoc debug entry, its DebugEntry.Type is also EFI_IMAGE_DEBUG_TYPE_CODEVIEW, its DEBUG_CODEVIEW_ ENTRY Signature is CODEVIEW_SIGNATURE_MTOC. So, it will be handled in this logic. for (Index = 0; Index < DebugDirectoryEntry->Size; Index += sizeof (EFI_IMAGE_DEBUG_DIRECTORY_ENTRY)) { // // Read next debug directory entry // Size = sizeof (EFI_IMAGE_DEBUG_DIRECTORY_ENTRY); ... // // From PeCoff spec, when DebugEntry.RVA == 0 means this debug info will not load into memory. // Here we will always load EFI_IMAGE_DEBUG_TYPE_CODEVIEW type debug info. so need adjust the // ImageContext->ImageSize when DebugEntry.RVA == 0. // if (DebugEntry.Type == EFI_IMAGE_DEBUG_TYPE_CODEVIEW) { ImageContext->DebugDirectoryEntryRva = (UINT32) (DebugDirectoryEntryRva + Index); if (DebugEntry.RVA == 0 && DebugEntry.FileOffset != 0) { ImageContext->ImageSize += DebugEntry.SizeOfData; } return RETURN_SUCCESS; } } Thanks Liming >-----Original Message----- >From: afish@apple.com [mailto:afish@apple.com] >Sent: Friday, August 11, 2017 1:08 PM >To: Gao, Liming <liming.gao@intel.com> >Cc: Kinney, Michael D <michael.d.kinney@intel.com>; edk2- >devel@lists.01.org >Subject: Re: [edk2] [Patch] BaseTools: Fix Segmentation fault: 11 when build >AppPkg with XCODE5 > > >> On Aug 10, 2017, at 9:48 PM, Gao, Liming <liming.gao@intel.com> wrote: >> >> Andrew: >> Edk2 Build system calls GenFw to generate EFI image in build phase.

This logic is here since the first version edk2 project. Per the comment, it should handle the one special PE image that was generated in the old compiler. For TE image, its image size is calculated by the RVA plus the VirtualSize of the last section mapped into memory. So, its image size should include the debug info. This is just my analysis. If there is such PE image, I can further verify this logic.

If so, the EFI image is always correct. There is no change requirement in PeCoff library in MdePkg. Liming, EFI supports loading PE/COFF images that are not built at the same time as the platform firmware (UEFI Shell, OS loader), and that is why I added the fix to the PE/COFF library code.
