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 100 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 in-between the calls.

Returns

Whether the compilation was successful

Definition at line 700 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 284 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 1131 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 1154 of file CompilerBase.hpp.

release_assignment()

template<IRAdaptor Adaptor, typename Derived, CompilerConfig Config>

void tpde::CompilerBase< Adaptor, Derived, Config >::release_assignment ( ValLocalIdx local_idx, ValueAssignment * assignment )

noexcept

Release an assignment when reference count drops to zero, either frees the assignment immediately or delays free to the end of the live range.

Definition at line 904 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 1453 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 759 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 164 of file CompilerBase.hpp.
