If we did not have 2 levels every place we had GCC wo= uld need XCODE and see the list [1]. Thus XCODE can use GCC when it is comp= atible with GCC (which is a majority of the time) and then use XCODE to hav= e XCODE rules that are different than GCC.=20 So I guess the way to describe it is XCODE inherits GCC and only needs to = override when it is different. As per usual we seem to have picked confusing names.=20 > In particular because in this patch, we don't use BUILDRULEFAMILY for > overrides in "build_rules.txt", we use BUILDRULEFAMILY for overrides in > DSC files. >=20 >=20 > Anyway, let's say that we use the following syntax for linker flag > overrides: >=20 > [BuildOptions.common.EDKII.DXE_RUNTIME_DRIVER] > GCC:*_*_*_DLINK_FLAGS =3D -z common-page-size=3D0x1000 > XCODE:*_*_*_DLINK_FLAGS =3D > CLANGPE: *_*_*_DLINK_FLAGS =3D /ALIGN:4096 >=20 > Fine. >=20 > But then, why don't we similarly use: >=20 > [BuildOptions] > GCC:*_*_*_CC_FLAGS =3D -mno-mmx -mno-sse > XCODE:*_*_*_CC_FLAGS =3D > CLANGPE:*_*_*_CC_FLAGS =3D >=20 > for CC flag overrides? >=20 > Because, the proposal is: >=20 > !if $(TOOL_CHAIN_TAG) !=3D "XCODE5" && $(TOOL_CHAIN_TAG) !=3D "CLANG9" > GCC:*_*_*_CC_FLAGS =3D -mno-mmx -mno-sse > !endif >=20 Is this really the same as: XCODE: *_*_*_CC_FLAGS =3D -mno-mmx -mno-sse GCC:*_CLANG8_*_CC_FLAGS =3D -mno-mmx -mno-sse Also for CLANG38 the above flags are part of CLANG38_ALL_CC_FLAGS.

Hi Liming,

1. Apply CLANG9 Linker option.

I'm confused by this, in two regards.
- Why do we refer to CLANG9 first as being in the GCC toolchain= family
(see near mmx/sse), and then under a totally differen= t family name
(CLANGPE?)

CLANGPE is used to override GCC option. GCC is used to append GCC op= tions. 
You= can see XCODE5 take the same way.&nb= sp;
CLANG9 tool chain doesn't recognize -z common-page= -size=3D0x1000 option. So, here CLANGPE is used to specify /ALIGN:4096 option. 
Wait, so the "GCC" toolchain *fa= mily* applies to:
- a= ctual GCC toolchains (such as GCC48, GCC49, GCC5)
- XCODE toolchains (such as XCODE5)
- CLANG toolchains (such as CLANG9)=

but the "X= CODE" toolchain *family* only applies to XCODE toolchains
(such as XCODE5), and similarly, the = CLANGPE toolchain *family* only
applies to CLANG toolchains (such as CLANG9)?

Put= differently, is XCODE in two toolchain families at the same time(GCC and XCODE)?

Similarly, is CLANG9 in two toolchain families at the same time (GCC and<= /span>
CLANGPE)?

Wait... from "BaseTools/Conf/tools_def.template":


#
#
# XCODE5 supp= ort
#

*_XCODE5_*_*_FAMILY  =           =3D GCC
*_XCODE5_*_*_BUILDRULEFAMILY   =3D XCODE

This makes me very = unhappy. I don't know how anyone can follow this.

What is t= he difference between "FAMILY" and "BUILDRULEFAMILY"?

When I see

  GCC:*_*_*_DLINK_FLAGS =3D -z comm= on-page-size=3D0x1000
&= nbsp; XCODE:*_*_*_DLINK_FLAGS =3D

how can I know that = the first line applies due to "FAMILY", but the
second line also applies due to "BUILDRULEFAMILY" = (and overrides the
fir= st line)?

Hmmm....

https://ed= k2-docs.gitbooks.io/edk-ii-build-specification/5_meta-data_file_specificati= ons/52_tools_def_txt.html

"""

Well, I can't say that it's entirely clear to me what app= lies when. :/


Laszlo,

If you just have  *_*_*_*_FAMILY then that matches the statements i= n the INF and DSC files (It also matters for build_rule.txt) like this exam= ple for GCC [1]. 

When you have&nb= sp;*_*_*_*_FAMILY and *_*_*_*_BUILDRULEFAMILY you get 2 levels. Thus X= CODE is generally compatible with GCC so it is in that *_*_*_*_FAMILY, but = if you need to do something XCODE specific you can use the XCODE *_*_*_*_BU= ILDRULEFAMILY. If we did not have 2 levels every place we had GCC would nee= d XCODE and see the list [1]. Thus XCODE can use GCC when it is compatible = with GCC (which is a majority of the time) and then use XCODE to have XCODE= rules that are different than GCC. 

So I guess the way to describe it is XCODE inherits GCC and only needs t= o override when it is different.

As per= usual we seem to have picked confusing names. 


= In particular because in this patch, we don't use BUILDRULEFAMILY fo= r
overrides in "build_r= ules.txt", we use BUILDRULEFAMILY for overrides in
DSC files.


Anyway, let's say that we use the following syntax for l= inker flag
overrides:

[BuildOptions.common.EDKII.DXE_RUNTIME_DRIVER]
 GCC:*_*_*_DLINK_FLAGS =3D -z c= ommon-page-size=3D0x1000
 XCODE:*_*_*_DLINK_FLAGS =3D
 CLANGPE: *_*_*_DLINK_FLAGS =3D /ALIGN:4096

Fine.

But then, why don't we similarly use:
[BuildOptions]
=  GCC:*_*_*_CC_FLAGS         &n= bsp;         =3D -mno-mmx -mno= -sse
 XCODE:*_*_*_= CC_FLAGS            =      =3D
 CLANGPE:*_*_*_CC_FLAGS      &n= bsp;        =3D

for= CC flag overrides?

Because, the proposal is:

!if $(TOOL_CHAIN_TAG) !=3D "XCODE5" && $(TOOL_CHAIN_TAG) != =3D "CLANG9"
 GCC= :*_*_*_CC_FLAGS           = ;        =3D -mno-mmx -mno-sse
!endif


Is this really the same as:
  XCODE: *_*_*_CC_FLAGS           &nbs= p;       =3D -mno-mmx -mno-sse
  GCC:*_CLANG8= _*_CC_FLAGS            =3D -mno-mmx -mno-sse<= /div>

Also for CLANG38 the above flags are pa= rt of CLANG38_ALL_CC_FLAGS. I they are needed then why are they not pa= rt of the generic tool chain definition?

Thanks,

Andrew Fish=

I mean, in one case (for the linker flags), we rely on B= UILDRULEFAMILY
for spec= ifying the override.

But in the other case (for the C comp= ilation flags), we do not rely on
BUILDRULEFAMILY; instead we check $(TOOL_CHAIN_TAG).
Is this difference justified? Why?


The rest of your answers sounds good to me. Thanks!<= /span>
