From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/ada/g-regexp.ads | 72 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 72 insertions(+) create mode 100644 gcc/ada/g-regexp.ads (limited to 'gcc/ada/g-regexp.ads') diff --git a/gcc/ada/g-regexp.ads b/gcc/ada/g-regexp.ads new file mode 100644 index 000000000..4300ebf40 --- /dev/null +++ b/gcc/ada/g-regexp.ads @@ -0,0 +1,72 @@ +------------------------------------------------------------------------------ +-- -- +-- GNAT COMPILER COMPONENTS -- +-- -- +-- G N A T .

It +-- is particularly useful for file name matching, and in particular +-- it provides "globbing patterns" that are useful in implementing +-- unix or DOS style wild card matching for file names. + +-- GNAT.Regpat (files g-regpat.ads/s-regpat.ads/g-regpat.adb) +-- This is a more complete implementation of Unix-style regular +-- expressions, copied from the original V7 style regular expression +-- library written in C by Henry Spencer. It is functionally the +-- same as this library, and uses the same internal data structures +-- stored in a binary compatible manner. + +-- GNAT.Spitbol.Patterns (files g-spipat.ads/g-spipat.adb) +-- This is a completely general pattern matching package based on the +-- pattern language of SNOBOL4, as implemented in SPITBOL. The pattern +-- language is modeled on context free grammars, with context sensitive +-- extensions that provide full (type 0) computational capabilities. + +with System.Regexp; + +package GNAT.Regexp renames System.Regexp; -- cgit v1.2.3
