Likely. I'd use the gimple_build () API from gimple-fold.h which
builds the expression(s) to a gimple_seq creating necessary temporaries

Thanks, I will have a look at this.
I am struggling to convert a uint32_type_node node to a gcov_type_node
(64-bit). I tried to use this:
if (result != NULL_TREE)
{
tree tmp1 = make_temp_ssa_name (gcov_type_node, NULL, name);
gassign *stmt7 = gimple_build_assign (result, VIEW_CONVERT_EXPR,
build1 (VIEW_CONVERT_EXPR, gcov_type_node,
high));
tree tmp2 = make_temp_ssa_name (gcov_type_node, NULL, name);
gassign *stmt8 = gimple_build_assign (tmp2, LSHIFT_EXPR, tmp1,
build_int_cst (integer_type_node, 32));
gassign *stmt9 = gimple_build_assign (result, BIT_IOR_EXPR, tmp2,
tmp1);
gsi_insert_after (gsi, stmt7, GSI_NEW_STMT);
gsi_insert_after (gsi, stmt8, GSI_NEW_STMT);
gsi_insert_after (gsi, stmt9, GSI_NEW_STMT);
}
This ends up in:
../test.c: In function 'f':
../test.c:4:1: error: conversion of register to a different size in
'view_convert_expr'

VIEW_CONVERT_EXPR<long long int>(PROF_time_profiler_15);
