The idea is to separate the notion of const from 'this variable can always be
replaced with its initializer' in the frontend. To do that, I introduced
Declaration::isSameAsInitializer, which is overridden in VarDeclaration to
return false for constants that have a struct literal initializer.
So
{{{
const S s = S(5);
void foo() { auto ps = &s; }
// is no longer replaced by
void foo() { auto ps = &(S(5)); }
}}}
To make taking the address of a struct constant with a struct-initializer
outside of function scope possible, I made sure that AddrExp::optimize doesn't
try to run the argument's optimization with WANTinterpret - that'd again
replace the constant with a struct literal temporary.
`available_externally` linkage. This allows the inliner to inline functions from
other modules while telling the code generator to ignore those functions (treat
them as declarations)
Still generates a few extra `TypeInfo`s and strings...
Disabled when generating debug info because I don't really understand it, and it
doesn't like this.
called on an `AliasDeclaration`; just printing the name will do. This fixes
#305, which otherwise tries to generate
{{{
class E {
void A() {
alias /* recurse into E->toCBuffer() */ m;
}
}
}}}
by way of an infinite recursion (causing a segfault when the stack runs out).
Fixed align N; in asm blocks.
Fixed inreg parameter passing on x86 for ref/out params.
Removed support for lazy initialization of function local static variables, I have no idea why I ever implemented this, it's not in the D spec, and DMD doesn't support it :P
Some of the global variable related changes might cause minor regressions, but they should be easily fixable.
Fixed function literals in static initializers.
Changed alignment of delegates from 2*PTRSIZE to just PTRSIZE.
Changed errors to go to stderr instead of stdout.
Fairly major rewriting of struct/union/class handling, STILL A BIT BUGGY !!!
Changed the way struct/class fields are added, first small part of cleaning up these...
Make struct/class/union fields aware of any anonymous struct/union they might be part of, not yet really useful, but part of getting better union support.
Fixed problems with label collisions when using labels inside inline asm. LabelStatement is now easily reached given its
Identifier, which should be useful elsewhere too.
Enabled inline asm for building the lib/compiler/llvmdc runtime code, fixing branches out of asm makes this possible.
Split up declaration, constant initializer gen and definition for globals, structs, classes and functions.
Improved ClassInfo support (not complete), not in vtable yet.
Fixed a bunch of forward reference problems.
Much more. Major commit! :)
Fixed some nested function problems when accessing outer function parameters.
Major changes to handling of structs.
Initial support for unions.
Probably more...
