Subject: gccrs: Fix narrowing of Loan (size_t) into LoanId (uint32)
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a887f69e96b7507173771526e20715c31c8f844f;p=thirdparty%2Fgcc.git

gccrs: Fix narrowing of Loan (size_t) into LoanId (uint32)

Fix narrowing:

  -../../gcc/rust/checks/errors/borrowck/rust-borrow-checker-diagnostics.cc:145:46:
  warning: narrowing conversion of ‘loan’ from ‘Rust::Polonius::Loan’ {aka
  ‘long unsigned int’} to ‘uint32_t’ {aka ‘unsigned int’} [-Wnarrowing]

gcc/rust/ChangeLog:
	* checks/errors/borrowck/rust-bir-place.h (LoanId::value): Make
	it size_t to match Loan's base type.
