Mike Gerwitz e6325c4c1d tamer: tests/xmli: Estimate tamec time in milliseconds
Going higher than that doesn't make sense because we're in shell and
invoking commands all around this, so even milliseconds isn't going to be
entirely accurate here.  However, what I am more interested in is observing
time relative to other runs; this isn't intended for profiling, but for
eyeballing unexpected behavior.

XMLI System Test

The xmli file is an intermediate file that serves as a handoff between TAMER and the XSLT-based compiler:

xml -> (TAMER) -> xmli -> (TAME XSLT) -> xmlo

TAMER gets the first shot at processing, and then the compilation process continues with the XSLT-based compiler. This allows TAMER to incrementally augment and manipulate the source file and remove responsibilities from TAME XSLT.

Tests in this directory ensure that this process is working as intended. TAMER's failure to perform a proper handoff will cause TAME XSLT to compile sources incorrectly, since TAMER will have rewritten them to something else.

This handoff is more than just echoing tokens back into a file---it derives a new program from the state of the ASG. This program may have a slightly different representation than the original sources, but it must express an equivalent program, and the program must be at least as performant when emitted by TAME XSLT.

Running Tests

Test are prefixed with test-* and are executable. They must be invoked with the environment variable PATH_TAMEC set to the path of tamec relative to the working directory.

Test cases are organized into sub-directories with src.xml and expected.xml files. src.xml will be compiled with tamec, its output formatted with xmllint --format, and diff'd against the xmllint-formatted output of expected.xml.
