+profilebucketsize
+profilebucketsize=[16|32]
This is a link-time option to support prof and gprof when building an executable, but
not a shared library. When prof or gprof startup code invokes sprofil, this option
specifies the size in bits of the counters used to record sampled values of the program
counter.
The effect of this option can be overridden by setting the environment variable
LD_PROFILEBUCKET_SIZE when running the instrumented program. This environment
variable has no effect when building the instrumented program. Legal values are 16 (the
default), and 32.
See gprof(1) and ld(1) manpages for more details.
Runtime Checking Options
The +check options allow you to check your application for errors at runtime.
+check
+check=all|none|bounds|globals|lock|malloc|stack|thread|truncate|uninit
The +check=xxx options provide runtime checks to detect many common coding errors
in the user program. These options introduce additional instructions for runtime checks
that can significantly slow down the user program. By default, a failed check will result
in the program aborting at the end of execution at runtime. In most cases, an error
message and a stack trace will be emitted to stderr before program termination. The
environment variable RTC_NO_ABORT can be set to 0, 1, or 2 to change the behavior
of failed runtime checks:
• 0 — A failed runtime check will abort the program immediately after the error
message is emitted.
• 1 — The default setting, which will abort the program at the end of execution upon
failure.
• 2 — A failed runtime check will not enable the end of execution abort.
The +check options need to be specified at both compile time and link time, since they
may require additional libraries to be linked into the user program. If different +check
options are specified while compiling different source files, all the specified +check
options are needed at link time.
Multiple +check options are interpreted left to right. In case of conflicting options, the
one on the right will override an earlier +check option.
