Branch target misalignment reduces performance by about 10%. | |||
2017-01-03 | Regularize timing code | Andrew Waterman | |
Provide get_timer_value() and get_timer_freq() and use them. On Arty, they use mcycle and the known-fixed core frequency, whereas on HiFive1 they use mtime and the known-fixed mtime frequency. | |||
2017-01-03 | Improve HiFive1 CPU frequency measurement routine | Andrew Waterman | |
- Warm up I$ first. - Correct for integer division truncation error. - Wait for an RTC clock edge before starting the timing loop, which removes an error proportional to the number of loop iterations, allowing us to run for far less time. | |||

Fixes in the root makefile | |||
2017-01-04 | Fixes in the root makefile | Quey-Liang Kao | |
Each cd command in the targets software, software_clean, and dasm is unnecessary. Also, fixes from make to $(MAKE) help the readability of build/dry-run output. | |||

And parameterize the help message on the default options. | |||
2016-12-20 | Completely ignore RISCV environment variable | Andrew Waterman | |
This Makefile installs the tools in a fixed location and ignores $RISCV, so $RISCV should not be used to set $PATH. The incorrect $PATH setting prevents the compiler from building, as it can't find the assembler. | |||
