YenHaoChen	4dfdf00f13	Let mstatus.MPP initially be M-mode if unsupporting U-mode This commit lets the mstatus.MPP be a valid value if unsupporting U-mode. Without this commit, the mret may result in a corrupted state without properly setting the MPP to M-mode (if unsupporting U-mode).	3 years ago
Andrew Waterman	8780656d5a	Merge pull request #1346 from Wojciech-Bartczak/spike-as-lib Install meta pkg-config file for Spike.	3 years ago
Wojciech Bartczak	7dbd0949c9	Add Spike's meta files for pkg-config This commit adds the *.pc files for Spike's simulation library, enabling dynamic and static linking without the need to directly reference Spike sources. Using Spike as a stand-alone library provides an interesting option for developing tools and applications based on Spike.	3 years ago

Philipp Tomsich	e25fb13bcd	Zfa: fix NX handling for the fround/froundnx family The initial implementation (together with the SAIL code and the tests) had gotten the NX variants backwards (as in 'an inexact result is ok' vs. 'set NX is inexact'). Update all 4 instructions. Signed-off-by: Philipp Tomsich <philipp.tomsich@vrull.eu>	3 years ago
Andrew Waterman	fcbdbe7946	Merge pull request #1316 from YenHaoChen/pr-native-triggers implement Debug Specification Section 5.4 Native Triggers	3 years ago
YenHaoChen	83c19daaf2	triggers: native triggers (action=0) should prevent causing a breakpoint exception while already in a trap handler This commit implements Debug Specification Section 5.4 Native Triggers. The specification allows two solutions for solving the reentrancy problem. This commit chooses the first solution because the second one targets implementations without S-mode.	3 years ago

Andrew Waterman	808fa1cab1	Avoid declaring potentially out-of-bounds references in vmfeq etc. I don't think this was actually broken, since the references weren't used, but it was certainly unsanitary. Fixes #1325	3 years ago

YenHaoChen	0b266f2a51	explicitly show D(-mode) instead of M(-mode) when in debug mode Debug mode (D-mode) can be considered an additional privilege mode. This commit proposes printing D(-mode) instead of M(-mode) for D-mode.	3 years ago
