-% We can start off with a couple of observations about the role of
-% compilers. First, hardware is getting weirder rather than getting
-% clocked faster: almost all processors are multicores and it looks
-% like there is increasing asymmetry in resources across
-% cores. Processors come with vector units, crypto accelerators, bit
-% twiddling instructions, and lots of features to make virtualization
-% and concurrency work. We have DSPs, GPUs, big.little, and Xeon
-% Phi. This is only scratching the surface. Second, we’re getting
-% tired of low-level languages and their associated security
-% disasters, we want to write new code, to whatever extent possible,
-% in safer, higher-level languages. Compilers are caught right in the
-% middle of these opposing trends: one of their main jobs is to help
-% bridge the large and growing gap between increasingly high-level
-% languages and increasingly wacky platforms. It’s effectively a
-% perpetual employment act for solid compiler hackers.
