* be: Let backends deal with memperm offsetsMatthias Braun2016-04-04
| | | | | | | | | Only the backends know how memperm are implementd and whether they use sp- or fp-relative addressing. This should fix sparc memperm problems. Long-term I'd like to remove the memperm node and use a callback that creates a sequence of target specific nodes instead (similar to how spills and reloads are created).
* be: Rewrite stack frame handlingMatthias Braun2016-04-04
| | | | | | | | | | | | | | | | | | | | This is a bigger rewrite of stack frame handling in the backend: - Do the stack frame type layout late, after all the spill slots have been created. This way we can avoid (and remove) the brittle frame_alloc_area(). - Standardize the meaning of stack entity offsets. After stack frame type layout they are relative to the stack pointer position at the beginning of the function. It is all in one type now, no splitting into "arg", "between" and "stack_frame" type anymore. - Generalize the stack pointer simulation code to work with a single callback. Represent stack state as current offset and align_padding number. Now that callbacks can access and modify them both we do not need custom code in the sparc backend anymore. - Remove alignment specification on IncSP, only keep a ignore_align flag used for the last IncSP that has to remove all existing sp adjustments and may end up on a misaligned SP on ia32/amd64. - Align stack by default on ia32+amd64 backends.

|
* Remove produces_sp register constraintMatthias Braun2015-07-01
| | | | | | | | We can easily identify the outputs producing a stack pointer by looking if the stack pointer register is assigned. Unfortunately this also needed a new mechanism to tell the verifier that some registers are not in SSA form (all the time) which needs a few extra lines in each backend.

* API change+fix for IncSP alignmentMatthias Braun2014-10-07
| | | | | | | | - alignment is set on each single IncSP now instead of a global arch_env setting - fixed ia32 not requesting any alignment anymore (even on darwin where we need it) - fixed amd64 creating IncSP nodes without flag_modifies_flags set
* remove support for trampolines/nested functionsMatthias Braun2014-09-19
| | | | | | - It was only available in the ia32 backend and broken there. As the feature is rarely used, I remove it for now instead of going through the trouble of fixing it.
* put irg link directly into node attributsMatthias Braun2014-09-17
| | | | | | | | | The previous approach put the irg link into the block attributes, so while saving memory an extra indirection was necessary. Some testing with valgrind massif+callgrind revealed that a direct link increses peak memory usage by ~1% while also increasing runtime by ~1%. More importantly the code gets a bit simpler and some strange corner cases can be removed with the direct link.

* split Sel node into Member and SelMatthias Braun2014-04-15
| | | | | | | | | - Compound type selection is performed with Member - Array indexing is performed with Sel - Instead of the simpleSel constructor functions you can use the normal Member constructors now - The concept of array element entities has been removed, Sel nodes just contain a pointer to the array type now.

* further cleanup in get/set_entity_irg/additional_propertiesMatthias Braun2013-10-31
| | | | | | | - Only allow get_entity_irg()/set_entity_irg() for method entities now. - Allow setting/getting of additional properties for method and alias entities. - Add some missing is_method_entity() checks in cgana.
* do not include config.h anymoreMatthias Braun2013-05-04
| | | | | | It has been empty for nearly all systems. People who used to put stuff in config.h can still create a config.h on their own and inject -include (gcc) or /FI (msvc) into their CPPFLAGS.

* big refactoring of arch_XXX functionsMatthias Braun2011-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | This tries to get the names in a consistent format. We basically have 2 views on register allocation/constraints now: 1) Register Requirements and Assigments are per-instruction. Each instruction has requirements on its inputs and outputs, register get assigned for outputs of an instruction (assignment is an attribute of an instruction, not of the Proj-nodes). The internal datastructures model this form! The functions here have the form: arch_get_irn_register_req_in(node, input_nr) arch_get_irn_register_in(node, input_nr) arch_get_irn_register_req_out(node, output_nr) arch_set_irn_register_out(node, output_nr, register) 2) Register Requirements and Assignments are on firm-values. This view allows to query/assign requirements and registers at the Proj nodes instead of the repsective predecessors. This is a convenience interface modeled on top of the other! The functions have the form: arch_get_irn_register_req(node) arch_get_irn_register(node) arch_set_irn_register(node, register)
