This reverts commit e5dbe24e942a32d4077a352b2634ef9acbbb669d. Reason for revert: Makes the Tint-Dawn roll fails because of MSL compilation errors on as_type<uint>(-2147483648): as_type cast from 'long' to 'uint' (aka 'unsigned int') is not allowed as_type<uint>(-2147483647) compiles fine, so this is most likely because the MSL compiler types the literal as a long (since without the - it is larger than the max int32). Original change's description: > MSL writer: make signed int overflow defined behaviour > > Bug: tint:124 > Change-Id: Icf545b633d6390ceb7f639e80111390005e311a1 > Reviewed-on: https://dawn-review.googlesource.com/c/tint/+/60100 > Kokoro: Kokoro <noreply+kokoro@google.com> > Commit-Queue: Antonio Maiorano <amaiorano@google.com> > Reviewed-by: David Neto <dneto@google.com> TBR=dneto@google.com,bclayton@google.com,jrprice@google.com,amaiorano@google.com,noreply+kokoro@google.com,tint-scoped@luci-project-accounts.iam.gserviceaccount.com Change-Id: I3e3384a9185013bb141a1b7b9b22bad8571bbc50 No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: tint:124 Reviewed-on: https://dawn-review.googlesource.com/c/tint/+/60345 Reviewed-by: Corentin Wallez <cwallez@chromium.org> Reviewed-by: Ben Clayton <bclayton@google.com> Auto-Submit: Corentin Wallez <cwallez@chromium.org> Commit-Queue: Ben Clayton <bclayton@google.com> Kokoro: Kokoro <noreply+kokoro@google.com>
