Updated dependencies: * GMP 6.2.1 * ISL 0.24 * MPL 1.2.1 * MPFR 4.1.0 The dependencies were pulled in by running the ./contrib/download_prerequisites script and then manually removing the symbolic links and archives, and renaming the directories (i.e mv isl-0.24 to isl)

# This script reads program output on STDIN, and out of it produces a block of
|
|
# dg-output lines that can be yanked at the end of a file. It will escape
|
|
# special ARE and Tcl constructs automatically.
|
|
#
|
|
# Each argument passed on the standard input is treated as a string to be
|
|
# replaced by ``.*'' in the final result. This is intended to mask out build
|
|
# paths, filenames, etc.
|
|
#
|
|
# Usage example:
|
|
|
|
# $ g++-13 -fcontracts -o test \
|
|
# 'g++.dg/contracts/contracts-access1.C' && \
|
|
# ./test |& dg-out-generator.pl 'g++.dg/contracts/contracts-access1.C'
|
|
# // { dg-output {contract violation in function Base::b at .*:11: pub > 0(\n|\r\n|\r)} }
|
|
# // { dg-output {\[level:default, role:default, continuation mode:never\](\n|\r\n|\r)} }
|
|
# // { dg-output {terminate called without an active exception(\n|\r\n|\r)} }
|
|
|
|
# You can now freely dump the above into your testcase.
