The new module discovery scheme requires the following section order:
.minfo_beg
.minfo
.minfo_end
This works for non-PIC code because the segments have the same attributes.
However, if -relocation-model=pic is passed to ldc2 then the .minfo section
becomes writeable and the sequence of sections is changed.
The quick fix is to mark the data always as writeable. Then all sections are
always writeable.
I think a better solution would be to base this in the used relocation model.
But this information is currently only available in the driver.
This fixes the failure in test case runnable/eh2.d
This is a replacement for the -noruntime switch. With the new DSO implementation
every module generates runtime calls. The main motivation for the -noruntime switch
is to avoid implicit GC calls. Therefore a dedicated -nogc switch is introduced.
If object.di was not read or is incomplete then basic types may be missing.
This results in a crash if they are used during runtime initialization.
This fixes#551.
The change not only makes the code cleaner but also fixes compilation of multiple files at once.
Previously, fd->nestedVars may have been filled twice if fd was a template function instantiated in two modules simultaneously.
Add some of the sanitizer passes to LDC. This is not complete (linking must be
done using clang and the right `-fsanitize=` option) and may not be useful at
all.
If it proves to be usefull then a lot of other options (e.g. blacklist) must be
added.
Adds some constructors and moves the code to the header file. Uses some of the new constructors.
A big problem with the source are the different strategies used for otherwise similar classes.
E.g. a IrField registers itself with the VarDeclaration. Same is required for IrParameter, but
in this case it is done by the caller.
The DMD implementation is a bit odd. A parameter is passed to the function but the function
itself is declared without a parameter. Then inline assembly is required to retrieve the
parameter.
Just do the same as gdc: declare the passed parameter.
