[PATCH 0/3] Arm*Pkg: convert LFs to CRLF, expand hard TABs

[PATCH 0/3] Arm*Pkg: convert LFs to CRLF, expand hard TABs

[Laszlo Ersek]

Bugzilla: https://bugzilla.tianocore.org/show_bug.cgi?id=1659
Repo:     https://github.com/lersek/edk2.git
Branch:   crlf_bz_1659

Future patches for some Arm*Pkg source files would either introduce CRLF
lines into LF files, or add more LF lines. The first would increase
inconsistency, the second would make "PatchCheck.py" yell. Convert these
files to CRLF uniformly (and while at it, expand hard TABS, because
"PatchCheck.py" catches those too).

[PATCH 1/3] ArmPkg: convert LFs to CRLF, expand hard TABs

[Laszlo Ersek]

We're going to switch the internal line terminators globally to LF at some
point, but until then, let's use CRLF consistently. Convert source files
with LFs in them to CRLF, using "unix2dos".

"git show -b" prints no code changes for this patch.

(I collected all the file name suffixes in this package, with:

$ git ls-files -- $PACKAGE | rev | cut -f 1 -d . | sort -u | rev

I eliminated those suffixes that didn't stand for text files, then
blanket-converted the rest with unix2dos. Finally, picked up the actual
changes with git-add.)

At the same time, the following three files had to undergo TAB expansion:

  ArmPkg/Library/ArmSoftFloatLib/ArmSoftFloatLib.c
  ArmPkg/Library/GccLto/liblto-aarch64.s
  ArmPkg/Library/GccLto/liblto-arm.s

I used "expand -t 2", in order to stay close to the edk2 coding style
(which uses two spaces for indentation.)

Both the CRLF conversion and the TAB expansion are motivated by
"PatchCheck.py". "PatchCheck.py" is also the reason why CRLF conversion
and TAB expansion have to happen in the same patch.

[PATCH 2/3] ArmVirtPkg: convert LFs to CRLF

[Laszlo Ersek]

We're going to switch the internal line terminators globally to LF at some
point, but until then, let's use CRLF consistently. Convert source files
with LFs in them to CRLF, using "unix2dos".

"git show -b" prints no code changes for this patch.

(I collected all the file name suffixes in this package, with:

$ git ls-files -- $PACKAGE | rev | cut -f 1 -d . | sort -u | rev

I eliminated those suffixes that didn't stand for text files, then
blanket-converted the rest with unix2dos. Finally, picked up the actual
changes with git-add.)

The CRLF conversion is motivated by "PatchCheck.py".

[PATCH 3/3] ArmPlatformPkg: convert LFs to CRLF, expand hard TABs

[Laszlo Ersek]

We're going to switch the internal line terminators globally to LF at some
point, but until then, let's use CRLF consistently. Convert source files
with LFs in them to CRLF, using "unix2dos".

"git show -b" prints no code changes for this patch.

(I collected all the file name suffixes in this package, with:

$ git ls-files -- $PACKAGE | rev | cut -f 1 -d . | sort -u | rev

I eliminated those suffixes that didn't stand for text files, then
blanket-converted the rest with unix2dos. Finally, picked up the actual
changes with git-add.)

At the same time, the following file had to undergo TAB expansion:

  ArmPlatformPkg/Scripts/Ds5/profile.py

I used "expand -t 4", conforming to the Indentation section of PEP-8
<https://www.python.org/dev/peps/pep-0008/#indentation>.

Both the CRLF conversion and the TAB expansion are motivated by
"PatchCheck.py". "PatchCheck.py" is also the reason why CRLF conversion
and TAB expansion have to happen in the same patch.
