See + typegmod.h and tpop.h for basic documentation of the change. + There now exists a type of kind type_id. If this appears + externally this is a bug. + + 9.7.2001 Goetz + Added some new access routines to types. + List of overwritten fields for entities. + Removed a bug in irnode. + + 4.7.2001 Goetz + Added a routine to set the mangled entity name. + Added two routines to copy entites. + + 3.7.2001 Goetz + Entities now have two more flags, for visibility and allocation mode. + Types that have a layout have a flag indicating whether the layout is + fixed. + + 25.6.2001 Goetz + We distinguish three kinds of Cond nodes. These can be distinguished + by the mode of the selector operand and an internal flag of type cond_kind. + First we distinguish binary Conds and switch Conds. + A binary Cond has as selector a boolean value. Proj(0) projects the control + flow for case "False", Proj(1) the control flow for "True". A binary Cond + is recognized by the boolean selector. + The switch Cond has as selector an unsigned integer. It produces as result + an n+1 Tuple (cf0, ... , cfn) of control flows. + We differ two flavours of this Cond. The first, the dense Cond, passes + control along output i if the selector value is i, 0 <= i <= n. If the + selector value is >n it passes control along output n. + The second Cond flavor differes in the treatment of cases not specified in + the source program. It magically knows about the existence of Proj nodes. + It only passes control along output i, 0 <= i <= n, if a node Proj(Cond, i) + exists. Else it passes control along output n (even if this Proj does not + exist.) This Cond we call "fragmentary". There is a special constructor + new_defaultProj that automatically sets the flavor. + The two switch flavors are distinguished by a flag of type cond_kind. + Default flavor is "dense" + + 20.6.2001 Goetz + Extended iropt, tv. + tv now implements Minus, Abs. + iropt now optimizes these and Div, Mod, Quot, DivMod. + Still missing: Shrs, Rot. + tarval_shr somtimes performs shrs, depending on the compiler/system!! + If the ArmRoq implementation is faulty there might appear errors. + + 20.6.2001 Goetz + Changed ircons: If undefined values are used the Phi construction + inserts a constant with value tarval_bad. + + 19.6.2001 Goetz + Changed array bounds in type.h to ir_node*. This allows to + construct array bounds that are complex constant expressions + simpler. Further dynamic array bounds can be displayed. + Comment in ircons.c extended: undefined values in start_block. + + 7.6.2001 Goetz + ifdef'ed all uses of gmp in tv.c away. Optimizations for + mode_Z no more supported, as well as constants of that mode. + + 7.6.2001 Goetz + Dokumentation in ir_dump + Habe Routinen fuer einzelne Knoten/Kanten aus header entfernt: + Benutzen globale Variable die nicht oeffentlich zugaenglich ist. + + 28.5.2001 Goetz + We need an entity for the array elements for the Sel nodes. This + entity should be stored in the array type. Changed constructor + parameters: include array element type. Entity for elements is built + automatically now. + + 28.5.2001 Goetz + Removed bug in tv.c. + Faulty use of va_arg, became visible with new, stricter gcc 2.96. + + 23.5.2001 Goetz + Added list of member entites to union. unioned_types and delimiters + are superfluous now -- removed. + Rationale: we want to express selection of a union member as a Sel + node. for this we need to have entities. The entities contain the + unioned type and have as name the delimiters... + + 17.4.2001 Boris + Changed Makefile/MakeTargets to install headers and libraries + seperately. + + 28.3.2001 Boris + Changed Makefile and Configure scripts to produce a proper tar file + for distribution (libfirm-VERSION.tar) + Use 'make distrib' instead of 'make dist' + + 14.3.2001 Goetz + Changed implementation of tr module. With this I also changed the + interface!! Type casts are unnecessary now, but some access funcions + differ. + + +====================================================================== +==================== New version: 0.3.0 ============================== +====================================================================== + + 14.3.2001 Boris + added file TODO + + 14.3.2001 Boris + added creation of a tar archive for distribution + replaced ir/.dummy.in by ir/Makefile.in + + 13.3.2001 Goetz + Changed equivalent_node() and copy_preds() so that the end block + is not optimized away if it has no real predecessors. This fixes + the problem with the while examples. + Added while_example in Makefile + + 12.3.2001 Goetz + Fooled around with if_while_example: Why does cse make it abort? + Cse removes path to End node, Bad remains as pred of Endblock. + The block walker can't deal with this. + Made new example with only loop: while_example. + + 12.3.2001 Boris + added auto documentation in Makefiles, configure, etc + example in ir/ir/ircons.c - much must be added + creation of documentation by 'make autodoc' in architecture directory + + 5.3.2001 Boris + added lots of #ifdef HAVE_CONFIG_G #include "config.h" #endif + replaced some C++ style comments (//) by standard C comments /**/ + added autoconf stuff + worked this night: + - configure (with some features, see --help for more) + - make [depend | tags | install] + - make [run] in testprograms + did not work: + - compilation on SunOS + - make dist + - automatic call of autoconf if required + 5.3.2001 Goetz More colours in vcg output. Fixed bug: cse found that start block equals it's
