Please split this patch up to a series so that *at the least* each
module is covered by a separate patch. For example,
1 MdeModulePkg/Application/CapsuleApp
2 MdeModulePkg/Application/UiApp
3 MdeModulePkg/Bus/Ata/AtaAtapiPassThru
4 MdeModulePkg/Bus/Isa/Ps2KeyboardDxe
5 MdeModulePkg/Bus/Pci/EhciDxe
6 MdeModulePkg/Bus/Pci/NvmExpressDxe
7 MdeModulePkg/Bus/Pci/PciBusDxe
8 MdeModulePkg/Bus/Pci/SdMmcPciHcDxe
9 MdeModulePkg/Bus/Pci/UhciPei
10 MdeModulePkg/Bus/Pci/XhciDxe
11 MdeModulePkg/Bus/Pci/XhciPei
12 MdeModulePkg/Bus/Sd/EmmcBlockIoPei
13 MdeModulePkg/Bus/Sd/SdBlockIoPei
14 MdeModulePkg/Bus/Ufs/UfsBlockIoPei
15 MdeModulePkg/Bus/Ufs/UfsPassThruDxe
16 MdeModulePkg/Bus/Usb/UsbBotPei
17 MdeModulePkg/Bus/Usb/UsbBusDxe
18 MdeModulePkg/Bus/Usb/UsbBusPei
19 MdeModulePkg/Core/Dxe
20 MdeModulePkg/Core/PiSmmCore
21 MdeModulePkg/Universal/Console/TerminalDxe
22 MdeModulePkg/Universal/HiiDatabaseDxe
23 MdeModulePkg/Universal/Network/IScsiDxe
24 MdeModulePkg/Universal/Network/Ip4Dxe
25 MdeModulePkg/Universal/Network/Tcp4Dxe
26 MdeModulePkg/Universal/SetupBrowserDxe
Removing 3358 lines, under a blanket "dead code" comment, across 26
drivers, is terribly bad practice, in my opinion. It's unreviewable, and
also unbisectable if something goes wrong.
The bug report <https://bugzilla.tianocore.org/show_bug.cgi?id=1062> states,
Uefi-aware compiler found many modules have dead code and redundant
definitions in the MdeModulePkg. Please see the detail info in the
attachment log. We need to clean them.
Because the module number is big, I report them all together by
package in this tracker and don't by modules separately.
Please be aware that there might be false positives in the log. The
Uefi-aware compiler currently only analyze the C code and has not
supported the assemble code yet. So, if a function is only invoked
by assemble code, the Uefi-aware compiler might miss it and report
it as dead code. Please verify them carefully if the module have
assemble code.
The bug report itself states that there might be false positives in the
log and that at least some cases have to be evaluated carefully. It's
exactly that evaluation that should be captured in each commit message.
The fact that the module number is big is *exactly* the reason why the
patch series should be fine-grained.
Many of these modules are consumed by most platforms in existence. If a
platform owner would like to take a look at a small subset of the
modules being modified here, they now have to dig around in a 3+ KLOC
patch, and figure it out for themselves *why* some code is called "dead".
Star, Eric, what are your takes on this? Do you agree with my request
above, or do you prefer the patch in its current form?
Thanks
Laszlo

Laszlo:
We manually search the unused functions in the module source files, and also verify the build to make sure the unused functions are real dead code. I agree to separate this patch as the module level. So, we can document which unused functions are removed in the driver.
Thanks

Works for me, but then the commit message should state exactly this.
Such as:
"""
Remove functions that have external linkage but are never called.
(We have manually verified that no function removed in this patch is
ever called.)
"""
Because:
* "Dead code" also means such code that is conditionally reachable (for
example, there is a conditional call to the function); however deeper
analysis reveals that the condition can never evaluate to TRUE.
A patch that eliminates code for this case must stand on its own,
because it needs non-mechanic review. From the commit message it
wasn't clear whether such changes were in scope, and it was difficult
to tell from the code (due to the size of the patch).
* "External linkage" is relevant because it highlights that the current
situation is at least in part the result of tooling limitations.
A large number of functions in MdeModulePkg should be STATIC (= be
given internal linkage), but they are kept with external linkage
because some VS debugging tools cannot cope with STATIC functions (to
my understanding).
In turn, because utility functions are never made STATIC, gcc cannot
emit warnings when some of those functions are never actually called
(if they were STATIC, gcc would abort the build with to warnings).
Obviously this doesn't apply to all utility functions (some may have
originally been called from multiple source files).

Thanks -- given the explanation above, I'd be fine with just a commit
message update. Still, if Shenglei has the time, I think that
module-level patching would be far better.
Thanks!

Could we *please* double check if this is still the case? Is this like
the ELILO thing, where nobody remembers what version exactly needed it
and we keep cargo culting (and duplicating) the fix ad inifitum?
IMO, STATIC is a fundamental part of careful structuring of your code,
and if the tooling cannot cope, it should be fixed.

Laszlo,
I agree for a patch like this that one patch
per module makes more sense.
We also need to make sure that this series is
tested with all supported compilers and CPU
architectures to make sure code is not being
removed that is required for a combination that
was missed.
Thanks,
Mike
