32 llvm-symbolizer \- convert addresses into source code locations
35 \fBllvm\-symbolizer\fP [\fIoptions\fP] [\fIaddresses...\fP]
38 \fBllvm\-symbolizer\fP reads input names and addresses from the command\-line
41 \fI\%\-\-filter\-markup\fP\&.
43 If no address is specified on the command\-line, it reads the addresses from
44 standard input. If no input name is specified on the command\-line, but addresses
49 input or as positional arguments on the command\-line. By default, input names
60 \fBllvm\-symbolizer\fP parses options from the environment variable
62 \fBLLVM_SYMBOLIZER_OPTS\fP is primarily useful for supplementing the command\-line
63 options when \fBllvm\-symbolizer\fP is invoked by another program or
68 use a mixture of C\-style and C++\-style linkage to illustrate how these names are
69 printed differently (see \fI\%\-\-demangle\fP).
115 $ clang \-g test.cpp \-o test.elf
116 $ clang \-g \-O2 test.cpp \-o inlined.elf
122 Example 1 \- addresses and object on command\-line:
128 $ llvm\-symbolizer \-\-obj=test.elf 0x4004d0 0x400490
139 Example 2 \- addresses on standard input:
149 $ llvm\-symbolizer \-\-obj=test.elf < addr.txt
163 Example 3 \- object specified with address:
169 $ llvm\-symbolizer \(dqtest.elf 0x400490\(dq \(dqFILE:inlined.elf 0x400480\(dq
180 $ llvm\-symbolizer < addr2.txt
191 Example 4 \- BUILDID and FILE prefixes:

297 Specify whether to use color in \fI\%\-\-filter\-markup\fP mode. Defaults to
298 \fBauto\fP, which detects whether standard output supports color. Specifying
299 \fB\-\-color\fP alone is equivalent to \fB\-\-color=always\fP\&.

412 Prints an address\(aqs debug\-data discriminator when it is non\-zero. One way to
413 produce discriminators is to compile with clang\(aqs \-fdebug\-info\-for\-profiling.
