Detailed Description

template<IRAdaptor Adaptor, typename Derived, CompilerConfig Config = CompilerConfigDefault>
struct tpde::CompilerBase< Adaptor, Derived, Config >

The base class for the compiler. It implements the main platform independent compilation logic and houses the analyzer

Definition at line 88 of file CompilerBase.hpp.

Member Function Documentation

compile()

template<IRAdaptor Adaptor, typename Derived , CompilerConfig Config>

bool tpde::CompilerBase< Adaptor, Derived, Config >::compile

(

)

Compile the functions returned by Adaptor::funcs

Warning

If you intend to call this multiple times, you must call reset inbetween the calls.

Returns

Whether the compilation was successful

Definition at line 664 of file CompilerBase.hpp.

derived()

template<IRAdaptor Adaptor, typename Derived , CompilerConfig Config = CompilerConfigDefault>

Derived * tpde::CompilerBase< Adaptor, Derived, Config >::derived ( )

inline

shortcut for casting to the Derived class so that overloading works

Definition at line 271 of file CompilerBase.hpp.

gval_as_reg()

template<IRAdaptor Adaptor, typename Derived , CompilerConfig Config>

CompilerBase< Adaptor, Derived, Config >::AsmReg tpde::CompilerBase< Adaptor, Derived, Config >::gval_as_reg ( GenericValuePart &  gv )

noexcept

Get generic value part into a single register, evaluating expressions and materializing immediates as required.

Definition at line 1100 of file CompilerBase.hpp.

gval_as_reg_reuse()

template<IRAdaptor Adaptor, typename Derived , CompilerConfig Config>

CompilerBase< Adaptor, Derived, Config >::AsmReg tpde::CompilerBase< Adaptor, Derived, Config >::gval_as_reg_reuse ( GenericValuePart &  gv, ScratchReg &  dst  )

noexcept

Like gval_as_reg; if the GenericValuePart owns a reusable register (either a ScratchReg, possibly due to materialization, or a reusable ValuePartRef), store it in dst.

Definition at line 1123 of file CompilerBase.hpp.

release_regs_after_return()

template<IRAdaptor Adaptor, typename Derived , CompilerConfig Config>

void tpde::CompilerBase< Adaptor, Derived, Config >::release_regs_after_return ( )

noexcept

When reaching a point in the function where no other blocks will be reached anymore, use this function to release register assignments after the end of that block so the compiler does not accidentally use registers which don't contain any values

Definition at line 1383 of file CompilerBase.hpp.

reset()

template<IRAdaptor Adaptor, typename Derived , CompilerConfig Config>

void tpde::CompilerBase< Adaptor, Derived, Config >::reset

(

)

Reset any leftover data from the previous compilation such that it will not affect the next compilation

Definition at line 723 of file CompilerBase.hpp.

Member Data Documentation

generating_branch

template<IRAdaptor Adaptor, typename Derived , CompilerConfig Config = CompilerConfigDefault>

bool tpde::CompilerBase< Adaptor, Derived, Config >::generating_branch = false

Whether we are currently in the middle of generating branch-related code and therefore must not change any value-related state.

Definition at line 152 of file CompilerBase.hpp.
