* Change the parser and printer so that they use IZR for real constants.Gravatar Guillaume Melquiond2017-03-22
| | | | | | | | | | | | | | | | | | | | | | There are two main issues. First, (-cst)%R is no longer syntactically equal to (-(cst))%R (though they are still convertible). This breaks some rewriting rules. Second, the ring/field_simplify tactics did not know how to refold real constants. This defect is no longer hidden by the pretty-printer, which makes these tactics almost unusable on goals containing large constants. This commit also modifies the ring/field tactics so that real constant reification is now constant time rather than linear. Note that there is now a bit of code duplication between z_syntax and r_syntax. This should be fixed once plugin interdependencies are supported. Ideally the r_syntax plugin should just disappear by declaring IZR as a coercion. Unfortunately the coercion mechanism is not powerful enough yet, be it for parsing (need the ability for a scope to delegate constant parsing to another scope) or printing (too many visible coercions left).
* Kills the useless tactic annotations "in |- *"Gravatar letouzey2012-07-05

* ZArith + other : favor the use of modern names instead of compat notationsGravatar letouzey2012-07-05
| | | | | | | | | | | | | | | | | | - For instance, refl_equal --> eq_refl - Npos, Zpos, Zneg now admit more uniform qualified aliases N.pos, Z.pos, Z.neg. - A new module BinInt.Pos2Z with results about injections from positive to Z - A result about Z.pow pushed in the generic layer - Zmult_le_compat_{r,l} --> Z.mul_le_mono_nonneg_{r,l} - Using tactic Z.le_elim instead of Zle_lt_or_eq - Some cleanup in ring, field, micromega (use of "Equivalence", "Proper" ...) - Some adaptions in QArith (for instance changed Qpower.Qpower_decomp) - In ZMake and ZMake, functor parameters are now named NN and ZZ instead of N and Z for avoiding confusions git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15515 85f007b7-540e-0410-9357-904b9bb8a0f7
