Subject: tests: check decoding of int 0x80 on x86_64, x32, and x86
X-Git-Tag: v4.17~157
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=a8a29266d8ebcb5c95760aa1aaf34fdbf55c4b2f;p=strace

tests: check decoding of int 0x80 on x86_64, x32, and x86

* tests/int_0x80.c: New file.
* tests/int_0x80.test: New test.
* tests/.gitignore: Add int_0x80.
* tests/Makefile.am (check_PROGRAMS): Likewise.
(MISC_TESTS, XFAIL_TESTS_x86_64, XFAIL_TESTS_x32): Add int_0x80.test.
(XFAIL_TESTS): Add $(XFAIL_TESTS_$(ARCH)).
(CLEANFILES): Add $(TESTS:=.tmp.out) and $(TESTS:=.tmp.exp).
