Compiler cache can greatly improve the build performance and
guarantee the build result safe. In our testing, the compiler
cache can improve the overall clean build time usually by 30+%
in linux and 10+% in windows. The compiler cache are very fit
to improve the Continuous Integration (CI) build performance.
For linux compiler cache (ccache) enabling, there is no need
to update edk2 code.
Below link has the ccache enabling referencd steps:
https://github.com/shijunjing/edk2/wiki/
Edk2-compiler-cache-enabling-steps-on-Linux
For windows compiler cache (clcache) enabling, we need update
the .PDB debugging file producing option from /Zi to /Z7,
which is to let the C object file contain its full symbolic
debugging information rather than produces a separated PDB file
for all obj files per folder. "PDB files are generated by a different
process (mspdbsrv). They arrive or are updated on disk after
cl completes a compilation or linking operation. One huge problem
with caching them is that the pdb files are input files as well as
outputs. mspdbsrv updates the file with new debug information if
the file exists beforehand. If there are several compilations going
on at once targetting the same pdb then the order the pdb gets
updated is unpredictable. All this makes caching very hard."
The /Zi issue more detail disccusion can be found:
https://github.com/frerich/clcache/issues/30
Please be aware that this change has no any impact to edk2 module
level PDB file generation, and we still can get the PDB debug file
for a .efi module. The /Z7 only impact intermediate obj files level
PDB file, which is current one PDB file (vc140.pdb) per obj folder.
Below link has the clcache enabling referencd steps:
https://github.com/shijunjing/edk2/wiki/
Edk2-compiler-cache-enabling-steps-on-Windows
Have tested below tools which consume the .PDB file:
*Edk2 source code debugger
*Various hardware and software debuggers
*Uefi code coverage tools
Only update and test below most commonly used four msvc toolchains:

"tools_def.template" currently suggests, in the documentation of the
LzmaF86Compress utility, that said tool is generally unhelpful on binaries
built with the GCC44 toolchain, relative to LzmaCompress.
This statement doesn't apply to the GCC48 toolchain. I compressed 126
NOOPT_GCC48/IA32 unique EFI modules (built with gcc-4.8.5, as part of
OVMF) with both LzmaCompress and LzmaF86Compress. I repeated the same for
117 NOOPT_GCC48/X64 unique EFI modules. On average, the LzmaF86Compress
output size was 92.4% of the LzmaCompress output size in the IA32 case
(best relative compression: 86.01%, poorest relative compression: 97.47%
-- still a win). In the X64 case, the LzmaF86Compress output size was
92.95% of the LzmaCompress output size, on avarege (best relative
compression: 87.69%, poorest relative compression: 97.65% -- again, still
a win).
Given the consistent improvement from LzmaCompress to LzmaF86Compress,
remove the statement (rather than updating it to GCC48).

GCC48_IA32_X64_DLINK_COMMON
GCC44_IA32_X64_DLINK_COMMON is only referenced by:
- GCC48_IA32_X64_ASLDLINK_FLAGS,
- GCC48_IA32_X64_DLINK_FLAGS.
Thus, we can rename ("raise") it to GCC48_IA32_X64_DLINK_COMMON.
(It's easier to review this patch with "git show --word-diff".)

- re-point all references of GCC44_IA32_X64_DLINK_FLAGS to

- remove GCC44_IA32_X64_DLINK_FLAGS.

DLINK_COMMON definitions are not consumed by "build_rule.template";
instead, DLINK_COMMON definitions (internal to "tools_def.template") were
invented for sharing options between ASLDLINK_FLAGS and DLINK_FLAGS.
However, this intent doesn't actually apply to
GCC48_IA32_X64_DLINK_COMMON: it is never consumed. Furthermore, the
GCC45..GCC47 instances of IA32_X64_DLINK_COMMON too lead up to
GCC48_IA32_X64_DLINK_COMMON only -- they form a dead-end. Remove them
altogether, in order to simplify the subsequent patches.

This drops ARM and AARCH64 support from the GCC46 and GCC47 toolchain
definitions, which are on the list to be removed, along with VS2003,
VS2005, VS2008, VS2010, DDK3790, UNIXGCC, GCC44, GCC45, ELFGCC, CYGGCC,

Since GCC46 and GCC47 are the only ones on that list that support ARM
and/or AARCH64, let's give Liming a hand and cover the ARM side of
things first, so that everything that remains to be removed is x86
only.

The 'arm-linux-gnueabihf' target triplet we use for CLANG35 and
CLANG38 specifies a hardfloat target, and so the binaries that are
emitted are annotated as using VFP registers for passing floating
point arguments, even though no VFP is used anywhere in the code.
This works fine as long as we don't try to link against code
that uses software floating point, but combining object files
with different floating point calling conventions is not permitted.
So switch to the softfloat arm-linux-gnueabi triplet instead.
This affects both the name Clang uses when invoking the linker,
and the arguments it passes to it, and we are mostly interested
in the latter (since any version of GNU ld.bfd will do the right
thing as long as it targets EABI ARM)
For native builds, this change has no effect, since the unprefixed
system linker will take priority, and so Clang will pass the right
arguments to whichever linker happens to be the system linker.
For cross builds, the fact that Clang composes the name of the
linker by prefixing '-ld' with the target triplet implies that
users will have to switch to a version of binutils that targets
arm-linux-gnueabi rather than arm-linux-gnueabihf. Note that the
GCCx toolchain targets can use either when building for ARM so this
does not create a need to install two versions of the ARM cross
toolchain. Also, note that all ARM toolchains in the GCC family
are already documented as requiring a toolchain that targets
arm-linux-gnueabi and not arm-linux-gnueabihf.

The ARM linker may emit veneers, i.e., trampolines, when ordinary
direct relative branches cannot be used, e.g., for Thumb interworking
or branch targets that are out of range.
Usually, such veneers carry an absolute reference to the branch
target, which is problematic for us, since these absolute references
are not covered by annotations that are visible to GenFw in the
PE/COFF conversion, and so these absolute references are not fixed
up by the PE/COFF loader at runtime.
So switch to all ARM GNU ld toolchains to position independent veneers.

PE/COFF only has a very limited id space for runtime relocations, and
so it defines only a single relocation for movw/movt instruction pairs,
which can be combined to load a 32-bit symbol reference into a register.
For this to work as expected, these instructions must always appear in
the same order and adjacently, and this is something few compilers take
into account, unless they target PE/COFF explicitly (and this is not the
case for our ELF based toolchains)
For Clang 3.6 and later, we can pass the -mno-movt option to suppress
movw/movt pairs entirely, which works around the issue. Unfortunately,
for Clang 3.5, the option is called differently (-mllvm -arm-use-movt=0)
and mutually incompatible between 3.5 and 3.6.
Since it is desirable for the CLANG35 toolchain to be usable on newer
versions of Clang as well (given that it is the only non-LTO alternative
to CLANG38), let's work around this issue in a way that permits versions
3.5 and newer of Clang to be used with the CLANG35 profile.
So pass the -mkernel flag instead (and add -Qunused-argument so Clang
does not complain about the -mno-unaligned-access in ARM_CC_XIPFLAGS).
This also inhibits movw/movt generation, along with some other changes
(e.g., long calls) which do affect code generation but not in an
undesirable manner.

We met a case on GCC toolchain for increment build. the case is user
build Helloworld first, then rename the source file Helloworld.c to
Helloworld_new.c and also update the file name to Helloworld_new.c in
.inf file's [sources] section. finally, he rebuild it again.
It cause build failure due to multiple definition of `UefiMain' because
in the .lib file it both have Helloworld.obj and Helloworld_new.obj.
current we use the option 'cr' to create the .lib file while the 'r'
cmd means replace existing or insert new files into the archive. so
in this patch before we create the .lib file, we delete it first.

As a security measure, some distros now build their GCC toolchains with
PIE code generation enabled by default, because it is a prerequisite
for ASLR to be enabled when running the executable.
This typically results in slightly larger code, but it also generates
ELF relocations that our tooling cannot deal with, so let's disable it
explicitly when using GCC49 or later for IA32. (Note that this does not
apply to X64: it uses PIE code deliberately in some cases, and our
tooling does deal with the resuling relocations)

The ElfConvert routines in GenFw don't handle the ".eh_frame" ELF section
emitted by gcc. For this reason, Leif disabled the generation of that
section for AARCH64 with "-fno-asynchronous-unwind-tables" in commit
28e80befa4fe [1], and Ard did the same for IA32 and X64 in commit
26ecc55c027d [2]. (The CLANG38 toolchain received the same flag at its
inception, in commit 6f756db5ea05 [3].)
However, ".eh_frame" is back now; in upstream gcc commit 9cbee213b579 [4]
(part of tag "gcc-8_1_0-release"), both "-fasynchronous-unwind-tables" and
"-funwind-tables" were made the default for AARCH64. (The patch author
described the effects on the gcc mailing list [5].) We have to counter the
latter flag with "-fno-unwind-tables", otherwise GenFw chokes on
".eh_frame" again (triggered for example on Fedora 28).
"-f[no-]unwind-tables" goes back to at least gcc-4.4 [6], so it's safe to
add to GCC_AARCH64_CC_FLAGS.

The crossing GCC compiler may use the different path for make and gcc tool.
So, GCC_HOST_BIN is introduced for make path. GCC5_BIN is still kept for
gcc path. User needs to set GCC_HOST_BIN besides set GCC5_BIN env if
the default make is not used. Normally, make is in the default system path.
GCC_HOST_BIN is not required to be set.
