Recently I started to see this fail with trunk: ... (gdb) record instruction-history^M 1 0x00000000004004ab <main+4>: call 0x4004b7 <test>^M 2 0x00000000004004c6 <test+15>: mov $0x1,%eax^M 3 0x00000000004004cb <test+20>: ret ^M (gdb) FAIL: gdb.btrace/tsx.exp: speculation indication ... This is due to an intel microcode update (1) that disables Intel TSX by default. Fix this by updating the pattern. Tested on x86_64-linux, with both gcc 7.5.0 and clang 12.0.1.
