Can you please test this in the environment where you wanted to use it
originally? (I assume you were using some kind of source level debugging.)
For that, you'll probably have to add NOOPT to BUILD_TARGETS in the
OvmfPkg/OvmfPkg*.dsc files. If you do that and everything works fine for
you, I'd appreciate if you could also submit the OvmfPkg patch to the list.
Thanks!

The patch looks good, but unfortunately for some reason it breaks
debugging using Andrei's gdb_uefi.py script: loading symbols fails:
The target architecture is assumed to be i386:x86-64:intel
0x000000007e65dec8 in ?? ()
Python Exception <class 'gdb.error'> No type named
EFI_SYSTEM_TABLE_POINTER.:
/home/bcran/.gdbinit:8: Error in sourced command file:
Error occurred in Python command: No type named EFI_SYSTEM_TABLE_POINTER.
I've verified that a DEBUG build with the same git checkout does still
work. I've looked through OvmfX64.dsc and couldn't see anything that
depends on DEBUG that would be omitting stuff for NOOPT, so I'm stuck.

Can you compare "DEBUG/GdbSyms.dll" with "NOOPT/GdbSyms.dll", just
visually, using "nm" and/or "readelf"? Something might stand out.

The NOOPT GdbSyms.dll file is missing the .gnu_debuglink section. It's
also missing ".LCx" (where x is 0 to 20) symbols in the .symtab section.

"BaseTools/Scripts/GccBase.lds" discards the gnu_debuglink section --
intentionally, from commit efe690cab3fb5 ("BaseTools GCC: add unified
GCC linker script for all archs and versions").
If this section is necessary for debugging, then why does the DEBUG
build work? In other words, why does the DEBUG build contain
gnu_debuglink despite the discard rule? Ard, any idea?
Thanks

tools_def.template contains a command to add it:
DEBUG_*_*_OBJCOPY_ADDDEBUGFLAG =
--add-gnu-debuglink=$(DEBUG_DIR)/$(MODULE_NAME).debug
I've followed up with the original email to say that adding a NOOPT line
fixes debugging for me.

In the section "GCC Common" there's
DEBUG_*_*_OBJCOPY_ADDDEBUGFLAG =
--add-gnu-debuglink=$(DEBUG_DIR)/$(MODULE_NAME).debug
RELEASE_*_*_OBJCOPY_ADDDEBUGFLAG =
A NOOPT line similar to the DEBUG one needs to be added for debugging to
work.
I've verified that by adding it the reload-uefi command runs and
single-stepping works.
