This is useful for enforcing that builds are independent of the environment; it can be used when all system library paths are added via /libpath: already. It's similar ot cl.exe's /X flag. Since it should also affect %LINK% (the other caller of `Process::GetEnv` in lld/COFF), the early-option-parsing needs to move around a bit. The options are: - Add a manual loop over the argv ArrayRef and look for "/lldignoreenv". This repeats the name of the flag in both Options.td and in DriverUtils.cpp. - Add yet another table.ParseArgs() call just for /lldignoreenv before adding %LINK%. - Use the existing early ParseArgs() that's there for --rsp-quoting and use it for /lldignoreenv for %LINK% as well. This means --rsp-quoting and /lldignoreenv can't be passed via %LINK%. I went with the third approach. Differential Revision: https://reviews.llvm.org/D67456 llvm-svn: 371852

ELF Improvements
|
|
----------------
|
|
|
|
* ...
|
|
|
|
COFF Improvements
|
|
-----------------
|
|
|
|
* /linkrepro: now takes the filename of the tar archive it writes, instead
|
|
of the name of a directory that a file called "repro.tar" is created in,
|
|
matching the behavior of ELF lld.
|
|
* The new `/lldignoreenv` flag makes lld-link ignore environment variables
|
|
like `%LIB%`.
|
|
* ...
|
|
|
|
MinGW Improvements

|

* ...

MachO Improvements

|
|
WebAssembly Improvements
|
|
------------------------
|
|
|
|
* `__data_end` and `__heap_base` are no longer exported by default,
|
|
as it's best to keep them internal when possible. They can be
|
|
explicitly exported with `--export=__data_end` and
|
|
`--export=__heap_base`, respectively.
