95c1d38e2e Integrate module gen/programs into driver/tool 2017-03-13 23:31:32 +01:00
Martin
cab165f3d8 Set up the MSVC environment in a more flexible way 
For invoking MS tools such as link.exe and lib.exe, which require
compatible PATH, LIB, LIBPATH etc.

We previously wrapped the invokation of the tool with a batch file taking
care of setting up the environment and then calling the actual tool.

I changed this to first invoke another batch file setting up its
environment and then dumping all environment variables to a file. LDC then
parses this file and updates its own environment variables. Later spawned
child processes then inherit the updated environment, and the tools will
be located by LLVM in updated PATH.

This allows LDC to keep track of the used Visual C++ installation (and
could so set up additional runtime libs required since VS 2015, something
we would have needed some time back when we still supported VS 2013). It's
also required as a prerequisite for integrating LLD as in-process linker
on Windows.

I quickly looked into the option of setting up the environment manually,
but the MS batch files are full of quirks, mixtures of registry and
file-system lookups, checking for existence of misc. headers to filter out
bogus installations etc. With VS 2017, there's nothing in the registry at
all anymore (at least for the Build Tools); MS expose a COM interface for
querying the VS installer... But at least they still provide the batch
files.

13218366b4 Don't necessarily enforce file extension of .bc, .ll, .s files 
Use the output filename (-of or inferred) directly if a single file is
emitted per compiled module.

Fixes issue #1843.

bb24fb2816 Add LTO support (full and thin), with -flto=thin|full. 
LTO needs linker support: I am only aware of support on OS X and Linux (through the LLVMgold plugin).

Resolves #693

29ce4012af dmd2 --> ddmd. Merge (almost all of) our changes to dmd source into the new D source of dmd 2.069.2. 
Also adds the CMake infrastructure to compile and link the D source files.

The build is partially broken:
- A few files in Phobos and druntime do not build
- MSVC build is broken because of unresolved symbols involving reals

This uses the LLVM style, which makes sense for sharing code
with other LLVM projects. The DMD code we use will soon all
be in D anyway.

0647f49aa5 driver: Mention size of allocas, do not repeat obvious types 
The latter is particularly helpful for readability of code with
deeply nested templates, i.e. huge type names.

bb32dcd6de Add new hidden option -no-integrated-as. 
This is useful if the integrated assembler causes problems.

Also adds an architecture to the assembler command line in case
of compiling for MIPS.

2331889669 MIPS: Implement ABI handling. 
Adds a new command line option -mabi= and uses the value to compute
the ABI to use. Adds the ABI to linker and assembler invocation, too.
