2017-11-17Enable building libitm with Intel CETIgor Tsimbalist7-4/+163

(GTM_longjmp): Add _CET_ENDBR. Restore Shadow Stack pointer. * config/x86/target.h (struct gtm_jmpbuf): Add new field for Shadow Stack pointer. * configure: Regenerate. * configure.ac: Set CET_FLAGS. Update XCFLAGS. * configure.ac: Update libtool_VERSION for x86. * testsuite/Makefile.in: Regenerate. From-SVN: r254908
2017-11-17Add extra field to gtm_jmpbuf on x86 onlyIgor Tsimbalist3-21/+32
Expand the gtm_jmpbuf structure by one word field to add Intel CET support further. The code in sjlj.S already allocates more space on the stack then gtm_jmpbuf needs. Use this extra space to absorb the new field. The structure is allocated on the stack in such a way that eip/rsp field is overlapped with return address on the stack. Locate the new field right before eip/rsp so code that accesses buffer fields relative to address of gtm_jmpbuf has its offsets unchanged. * libitm/config/x86/target.h: Add new field (ssp). * libitm/config/x86/sjlj.S: Change offsets.

The attached patch adds the a target specific attribute via the new target macro TARGET_BEGIN_TRANSACTION_ATTRIBUTE to the function begin_transaction(). S/390 uses this to set the soft-float target attribute which is needed to fix a crash with -m31. As there seems to be no place in libitm to document internal macros like USE_HTM_FASTPATH or the new macro, I've put the documentation in a comment where the macro is used. 2016-03-03 Dominik Vogt <vogt@linux.vnet.ibm.com> * config/s390/target.h (TARGET_BEGIN_TRANSACTION_ATTRIBUTE): Define function attribute to disable floating point in begin_transaction() on S/390. * beginend.cc (begin_transaction): Use TARGET_BEGIN_TRANSACTION_ATTRIBUTE.

2015-10-09Testsuite: add dg-{begin|end}-multiline-output commandsDavid Malcolm2-0/+6
This patch adds an easy way to write tests for expected multiline output. For example we can test carets and underlines for a particular diagnostic with: /* { dg-begin-multiline-output "" } typedef struct _GMutex GMutex; ^~~~~~~ { dg-end-multiline-output "" } */ multiline.exp is used by prune.exp; hence we need to load it before prune.exp via *load_gcc_lib* for the testsuites of the various non-"gcc" support libraries (e.g. boehm-gc). gcc/testsuite/ChangeLog: * lib/multiline.exp: New file. * lib/prune.exp: Load multiline.exp. (prune_gcc_output): Call into multiline.exp to handle any multiline output directives. * lib/libgo.exp: Load multiline.exp before prune.exp, using load_gcc_lib. boehm-gc/ChangeLog: * testsuite/lib/boehm-gc.exp: Load multiline.exp before prune.exp, using load_gcc_lib. libatomic/ChangeLog: * testsuite/lib/libatomic.exp: Load multiline.exp before prune.exp, using load_gcc_lib. libgomp/ChangeLog: * testsuite/lib/libgomp.exp: Load multiline.exp before prune.exp, using load_gcc_lib. libitm/ChangeLog: * testsuite/lib/libitm.exp: Load multiline.exp before prune.exp, using load_gcc_lib. libvtv/ChangeLog: * testsuite/lib/libvtv.exp: Load multiline.exp before prune.exp, using load_gcc_lib.
