206/** Number of EFLAGS bits we put aside for the hardware EFLAGS, with the bits
207 * above this we use for storing internal state not visible to the guest.
208 *
209 * Using a value less than 32 here means some code bloat when loading and
210 * fetching the hardware EFLAGS value. Comparing VMMR0.r0 text size when
211 * compiling release build using gcc 11.3.1 on linux:
212 * - 32 bits: 2475709 bytes
213 * - 24 bits: 2482069 bytes; +6360 bytes.
214 * - 22 bits: 2482261 bytes; +6552 bytes.
215 * Same for windows (virtual size of .text):
216 * - 32 bits: 1498502 bytes
217 * - 24 bits: 1502278 bytes; +3776 bytes.
218 * - 22 bits: 1502198 bytes; +3696 bytes.
219 *
220 * In addition we pass pointer the 32-bit EFLAGS to a number of IEM assembly
221 * functions, so it would be safer to not store anything in the lower 32 bits.
222 * OTOH, we'd sooner discover buggy assembly code by doing so, as we've had one
223 * example of accidental EFLAGS trashing by these functions already.
224 *
225 * It would be more efficient for IEM to store the interrupt shadow bit (and
226 * anything else that needs to be cleared at the same time) in the 30:22 bit
227 * range, because that would allow using a simple AND imm32 instruction on x86
228 * and a MOVN imm16,16 instruction to load the constant on ARM64 (assuming the
229 * other flag needing clearing is RF (bit 16)). Putting it in the 63:32 range
230 * means we that on x86 we'll either use a memory variant of AND or require a
231 * separate load instruction for the immediate, whereas on ARM we'll need more
232 * instructions to construct the immediate value.
233 *
234 * Comparing the instruction exit thruput via the bs2-test-1 testcase, there
235 * seems to be little difference between 32 and 24 here (best results out of 9
236 * runs on Linux/VT-x). So, unless the results are really wrong and there is
237 * clear drop in thruput, it would on the whole make the most sense to use 24
238 * here.
239 *
240 * Update: We need more than 8 bits because of DBGF, so using 22 now.
